The recess (508) can prevent an adhesive material (611), such as UV epoxy, for attaching the filter (610) to the seating portion (500) from overflowing out of the seating portion (500).

[0096] For example, the recess (508) may include a plurality (e.g., 4) recesses (5A to 5D) formed in a plurality (e.g., 4) corner regions of the seating portion (500), but is not limited thereto, and in other embodiments, the recess may be formed in at least one of the plurality of corners of the seating portion (400).

[0097] The opening (501) of the holder (600) can be formed on the bottom surface (11) of the seating portion (500).

[0098] The holder (600) is provided on the outer surface (52) and may have at least one groove (24a, 24b) that is recessed from the outer surface (52). Here, the groove (504) may be replaced with "recessed" or "groove".

[0099] For example, the holder (600) may include four outer surfaces, and may include a first groove (24a) and a second groove (24b) that are spaced apart from each other and may be formed on any one of the outer surfaces.

[0100] The first and second grooves (24a, 24b) may correspond to or face the terminals (164-1, 164-2) of the first and second elastic members (160-1, 160-2) of the lower elastic member (160).

[0101] Each of the first and second grooves (24a, 24b) may include an upper opening that opens to the upper surface (51a) of the holder (600) and a lower opening that opens to the lower surface (51b) of the holder (600).

[0102] The first and second grooves (24a, 24b) of the holder (600) may correspond to or opposite to grooves (22A, 22B) formed on the outer surface of the base (210) of the lens driving device (100).

[0103] The holder (600) may include a protrusion (604) protruding from the lower surface (51b).

[0104] For example, the lower surface (51b) of the holder (600) may be a surface located opposite the upper surface (51a) of the holder (600).

[0105] The protrusion (604) of the holder (600) can be positioned to be connected to or in contact with the edge of the lower surface (52b) of the holder (600), and can be in contact with the outer surface of the holder (600).

[0106] The shape of the protrusion (604) viewed from below may be a polygon (e.g., a square).

[0107] An adhesive member for joining the holder (600) and the circuit board (800) may be disposed between the lower surface (51c) of the protrusion (604) of the holder (600) and the upper surface of the circuit board (800). For example, the adhesive member may be a thermosetting adhesive member, such as a thermosetting epoxy.

[0108] On the lower surface (51c) of the protrusion (604) of the holder (600), a projection (48) may be formed to be coupled with a groove or hole (93, see FIG. 5) formed in the circuit board (800).

[0109] The filter (610) can be placed within the seating portion (500) of the holder (600).

[0110] For example, the filter (610) may be placed or seated on the bottom surface (11) of the seating portion (500). For example, the lower surface of the filter (610) may be in contact with or attached to the bottom surface (12) of the seating portion (500).

[0111] For example, the adhesive member (611) may be placed on the bottom surface (11) of the mounting portion (500), and the edge of the lower surface of the filter (610) may be attached or fixed to the bottom surface (11) of the mounting portion (500) by the adhesive member (611).

[0112] For example, the adhesive member (611) may be epoxy, a thermosetting adhesive (e.g., thermosetting epoxy), or a UV-curable adhesive (e.g., UV-curable epoxy).

[0113] The filter (610) may have a plate shape, a flat rectangular shape, or a polyhedron shape (e.g., a hexahedron), but is not limited thereto.

[0114] The shape of the mounting portion (500) viewed from above may match the shape of the filter (610) or have a shape suitable for accommodating the filter (610). For example, the shape of the mounting portion (500) viewed from above may be polygonal (e.g., square), circular, or elliptical, but is not limited thereto.

[0115] For example, the shape of the opening (501) of the holder (600) may match the shape of the filter (610) or the image sensor (810), but is not limited thereto.

[0116] Light passing through the lens module (400) can pass through the filter (610) and be incident on the image sensor (810).

[0117] The filter (610) can serve to block light of a specific frequency band from passing through the lens module (400) from entering the image sensor (810). For example, the filter (610) may be an infrared blocking filter, but is not limited thereto, and in other embodiments, the filter may be an infrared passing filter. For example, the filter (610) may be positioned parallel to the xy plane perpendicular to the optical axis (OA).

[0118] The adhesive member (612) can combine or attach the base (210) of the lens driving device (100) to the holder (600). For example, the second adhesive member (612) can be placed between the lower surface of the base (210) and the upper surface (51a) of the holder (600), and can bond the two together.

[0119] In addition to the adhesive role described above, the adhesive member (612) may also serve to prevent foreign substances from entering the lens driving device (100). For example, the adhesive member (612) may be an epoxy, a thermosetting adhesive, or a UV-curing adhesive.

[0120] For example, the adhesive member (612) may be placed on the upper surface of the holder (600) to have a ring shape that surrounds the opening (501) of the holder (600), but is not limited thereto.

[0121] The holder (600) is placed on the circuit board (800) and can support the lens driving device (100). For example, the lower surface of the base (210) of the lens driving device (100) and the upper surface of the holder (600) may face each other in the direction of the optical axis, and the two may be attached to each other by an adhesive member (612).

[0122] The circuit board (190) may be a printed circuit board (PCB).

[0123] A circuit board (190) may be placed under a holder (600) and may include a first board (191), a second board (192), a third board (193) connecting the first board (191) and the second board (192), and a connector (194) connected to the third board (193).

[0124] The holder (600) can be attached or fixed to the upper surface of the circuit board (800) by means of an adhesive member (not shown), such as epoxy, thermosetting adhesive, UV-curing adhesive, etc. At this time, the adhesive member may be positioned between the lower surface of the holder (600) and the upper surface of the circuit board (800).

[0125] The image sensor (810) and circuit element (95) can be placed or mounted on the circuit board (800).

[0126] For example, a circuit element (85) may be placed or mounted on the first substrate (191). Additionally, the circuit board (190) may include at least one terminal placed or formed on the first substrate (191).

[0127] For example, the number of terminals on the circuit board (190) may be multiple, and the multiple terminals of the circuit board (190) may be electrically connected to the image sensor (810) and the circuit element (95).

[0128] A sensor base (600), an image sensor (810), and a circuit element (95) may be disposed on the first substrate (191). For example, the first substrate (191) and the second substrate (192) may be rigid printed circuit boards, and the third substrate (193) may be a flexible printed circuit board that electrically connects the first substrate (191) and the second substrate (192), but is not limited thereto, and in other embodiments, at least one of the first to third substrates may be a rigid printed circuit board or a flexible printed circuit board. In yet another embodiment, the first to third substrates may be a single substrate implemented as a single unit.

[0129] The image sensor (810) may be mounted on a circuit board (800) and electrically connected to a circuit board (190). The image sensor (810) may include an active area (or effective image area or imaging area) (see 811 in FIG. 10b) where light passing through a filter (610) is incident and an image containing the light is formed.

[0130] The image sensor (810) can convert light irradiated onto the active area (811) into an electrical signal and output the converted electrical signal.

[0131] The optical axis of the image sensor (810) and the optical axis of the lens module (400) can be aligned.

[0132] For example, the active area (811) of the filter (610) and the image sensor (810) may be spaced apart so as to face each other in the direction of the optical axis (OA).

[0133] The circuit element (95) may be electrically connected to the first substrate (191) and may include a control unit that controls the image sensor (160) and the first lens unit (130). For example, the circuit element (95) may include at least one of a capacitor, a memory, a controller, a sensor (e.g., a motion sensor), or an IC (Integrated Circuit).

[0134] The circuit board (800) can be electrically connected to the lens driving device (100).

[0135] For example, the circuit board (800) may be electrically connected to the first and second elastic members (160-1, 160-2) of the lens driving device (100). For example, the circuit board (800) may include terminals (19A, 19B) that are electrically connected to the first and second elastic members (160-1, 160-2) of the lens driving device (100) by solder (35A, 35B).

[0136] Alternatively, in another embodiment, the circuit board (800) may be electrically connected to the circuit board of the lens driving device.

[0137] For example, a driving signal may be provided to the coil (120) of the lens driving device (100) through the circuit board (800). Alternatively, in another embodiment, a driving signal may be provided to the AF position sensor (or OIS position sensor) through the circuit board (800). Additionally, the output of the AF position sensor (or / and OIS position sensor) may be transmitted to the circuit board (800).

[0138] The connector (194) is electrically connected to a circuit board (800), such as a second board (192), and may have a port for electrically connecting to an external device.

[0139] Although not illustrated in FIG. 1, other embodiments may further include a reinforcing material disposed below the circuit board (800) and attached to the lower surface of the circuit board (800) and the lower surface of the image sensor. In this case, the reinforcing material is a plate-shaped member having a predetermined thickness and hardness, capable of sealing through holes in the circuit board (800), stably supporting the circuit board and the image sensor, and preventing damage to the circuit board due to external impact or contact. Additionally, the reinforcing material can enhance the heat dissipation effect of releasing heat generated from the image sensor to the outside.

[0140] For example, the reinforcing material may be formed from a metal material with high thermal conductivity, such as SUS or aluminum, but is not limited thereto. In other embodiments, the reinforcing material may be formed from glass epoxy, plastic, or synthetic resin.

[0141] In an embodiment where a reinforcing material is provided, the circuit board (800) may include an opening or a through hole, and an image sensor may be placed within the opening or through hole of the circuit board, and an image sensor (810) may be placed on the upper surface of the reinforcing material.

[0142] In addition, the reinforcing material may serve as a ground to protect the camera module from ESD (Electrostatic Discharge Protection) by being electrically connected to the ground terminal of the circuit board (800).

[0143] The foreign matter adsorption part (310) may be placed on or coupled to the upper surface of the filter (610). Here, the upper surface of the filter (610) may be a surface facing the lens module (400) in the direction of the optical axis. The foreign matter adsorption part (310) may be referred to as an "adsorption part," a "foreign matter adhesion part," or a dust trap.

[0144] The foreign matter adsorption part (310) may have an opening, such as a through hole, provided at a position corresponding to the image sensor (810).

[0145] The foreign matter adsorption part (310) may be placed in the edge area of ​​the upper surface (62) of the filter (610). For example, the foreign matter adsorption part (310) may be coupled or attached to the edge area of ​​the upper surface (62) of the filter (610).

[0146] For example, the filter (610) can be formed as a polygon, for example, a square, when viewed in the direction of the optical axis.

[0147] For example, the foreign matter adsorption part (310) may have a polygonal shape, for example, a square shape. The foreign matter adsorption part (310) may have a closed curve or a ring shape, but is not limited thereto. For example, the foreign matter adsorption part may have a closed curve shape with a polygonal, for example, a square shape opening, but is not limited thereto.

[0148] The foreign matter adsorption portion (310) may be formed symmetrically with respect to the filter (610) along each side of the upper surface of the filter (610). For example, the foreign matter adsorption portion (310) may be formed symmetrically left and right or symmetrically up and down with respect to the filter (610).

[0149] For example, the foreign matter adsorption portion (310) may be formed to have a constant width on each side of the upper surface of the filter (610), but is not limited thereto.

[0150] In FIG. 10a and FIG. 10b, the foreign matter adsorption part (310) is placed on the upper surface of the filter (310), but is not limited thereto. In other embodiments, the foreign matter adsorption part may be placed on the upper surface of the filter (310) and on the side of the filter (310). For example, in other embodiments, the foreign matter adsorption part may be placed between the side of the filter (310) and the inner surface (12) of the seating part (500) of the holder (600), and the foreign matter adsorption effect and light blocking effect may be improved.

[0151] Referring to FIG. 10a and FIG. 10b, for example, the side (61) of the filter (610) may be spaced apart from the inner side (12) of the seating portion (500) of the holder (600).

[0152] For example, the upper surface (62) of the filter (610) may be positioned lower than the upper surface (51a) of the holder (600) in the direction of the optical axis. Alternatively, for example, the upper surface (62) of the filter (610) may be positioned lower than the bottom surface of the foreign matter collection unit (506). This is to avoid spatial interference between the lens module (400) and the filter (610).

[0153] For example, the height of the upper surface of the foreign matter adsorption part (310) relative to the bottom surface (11) of the seating part (500) may be lower than the upper surface (51a) of the holder (600) and / or the bottom surface of the foreign matter collection part (506), but is not limited thereto. In other embodiments, the former may be higher than or at the same height as the latter.

[0154] The holder (600) may include a first inclined surface (607) and a second inclined surface (609) located between the lower surface (51b) and the bottom surface (11) of the seating portion (500).

[0155] The first inclined surface (607) may be in contact with the bottom surface (11) of the mounting portion (500) and may be an inclined surface inclined downward from the bottom surface (11). For example, the angle formed between the first inclined surface (607) of the holder (600) and the bottom surface (11) may be an obtuse angle. For example, the first inclined surface (607) may be a tapered surface. The first inclined surface (607) can prevent cracks from occurring due to collision between the lower surface of the filter (610) and the mounting portion (500) of the holder (600).

[0156] The second inclined surface (609) may be in contact with the lower surface (51b) of the holder (600) and may be an inclined surface inclined upward from the lower surface (51b) of the holder (600). For example, the interior angle formed by the second inclined surface (609) of the holder (600) and the lower surface (51b) of the holder (600) may be an obtuse angle.

[0157] Additionally, the holder (600) may further include a third inclined surface (608) connecting the first inclined surface (607) and the second inclined surface (609). For example, the third inclined surface (608) may be perpendicular with respect to the bottom surface (11), but is not limited thereto, and in other embodiments, the angle at which the third inclined surface (608) is tilted with respect to the bottom surface (11) may be obtuse or acute.

[0158] The side or outer surface of the foreign matter adsorption part (310) may be in the same plane as the side (61) of the filter (610). For example, the side or outer surface of the foreign matter adsorption part (310) may be in contact with the side of the filter (610), but is not limited thereto. In other embodiments, the side of the foreign matter adsorption part (310) may not be in the same plane as the side (61) of the filter (610), and the side of the foreign matter adsorption part (310) may be spaced apart from the side (61) of the filter (610) or from the corner where the side of the filter (610) and the upper surface of the filter (610) come into contact.

[0159] For example, the foreign matter adsorption portion (310) may be spaced apart from the inner surface (12) of the seating portion (500) of the holder (600).

[0160] When viewed from above, the foreign matter adsorption part (310) may overlap at least a portion with the bottom surface (11) of the mounting part (500) in the direction of the optical axis.

[0161] Additionally, the foreign matter adsorption portion (310) may overlap with the adhesive member (612) when viewed from above or in the direction of the optical axis.

[0162] For example, the width of the foreign matter adsorption part (310) may be greater than the width of the bottom surface (11) of the seating part (500). Or, for example, in another embodiment, the width of the foreign matter adsorption part (310) may be the same as or smaller than the width of the bottom surface (11) of the seating part (500).

[0163] Additionally, for example, the width of the foreign matter adsorption portion (310) may be greater than the width of the adhesive member (612). Or, for example, in another embodiment, the width of the foreign matter adsorption portion may be the same as or smaller than the width of the adhesive member (612).

[0164] Additionally, the foreign matter adsorption portion (310) may overlap with at least a portion of the image sensor (810) when viewed from above or in the direction of the optical axis.

[0165] Additionally, the foreign substance adsorption portion (310) may not overlap with the active area (811) of the image sensor (810) when viewed from above or in the optical axis direction, but is not limited thereto. In other embodiments, the foreign substance adsorption portion (310) may overlap with the active area (811) of the image sensor (810) when viewed from above or in the optical axis direction.

[0166] The foreign matter adsorption part (310) may be made of an adhesive material or an adhesive material. For example, the foreign matter adsorption part (310) may be formed by applying or attaching a material of an adhesive component that causes foreign matter to stick to one area of ​​the upper surface (62) of the filter (610).

[0167] For example, the adhesive material may be a dust trap agent, adhesive silicone, or adhesive resin, but is not limited thereto.

[0168] For example, the foreign matter adsorption part (310) can be attached to or fixed to the filter in the form of a film or double-sided tape.

[0169] For example, the adhesive material for forming the foreign matter adsorption part (310) may be a material whose adhesiveness does not significantly decrease over time.

[0170] When assembling a camera module, numerous foreign substances generated from the lens driving device, etc., or introduced from the outside, may naturally adhere to the image sensor. If these foreign substances, such as dust, are transferred to the pixels of the active area of ​​the image sensor, defects, such as stains, may occur on the final screen of the device containing the camera module.

[0171] The foreign matter collection portion of the holder (600) can remove such foreign matter, but the size of the holder may be increased to secure an area for forming the foreign matter collection portion. Alternatively, if the size of the foreign matter collection portion is increased, the area of ​​the upper surface of the holder excluding the foreign matter collection portion is relatively reduced. A reduction in the upper surface of the holder causes a reduction in the application area of ​​the adhesive member, and as a result, the adhesive force between the holder and the base of the lens driving device may be weakened.

[0172] In addition, since the foreign matter collection unit is provided in the holder, it may be difficult for the foreign matter collection unit to collect foreign matter entering the image sensor from the filter or the upper side of the filter.

[0173] Since the foreign matter adsorption part (310) is separately placed on the upper surface of the filter (610), the embodiment can achieve the following effects.

[0174] First, foreign matter can be collected in close proximity to the active area (811) of the image sensor (810), and thereby the stain defect rate of the image sensor (810) caused by foreign matter can be reduced.

[0175] Next, if necessary, the area of ​​the foreign matter collection section formed in the holder (600) may be reduced, or the foreign matter collection section may not be formed in the holder (600). This can improve the design freedom of the holder (600).

[0176] In addition, the upper surface area of ​​the holder (600) for applying the adhesive material can be sufficiently secured, thereby preventing weakening of the bonding force between the holder and the base.

[0177] The foreign matter adsorption part (310) may be formed of a transparent material, but is not limited thereto. In other embodiments, it may be formed of an opaque material.

[0178] For example, the foreign matter adsorption part (310) may be positioned at the edge area of ​​the upper surface of the filter (610) and may be a light blocking member that blocks at least a portion of the light passing through the lens module (400) from passing through the edge area of ​​the filter (610).

[0179] For example, the foreign matter adsorption part (310) may be formed of an opaque material, but is not limited thereto. For example, the foreign matter adsorption part (310) may be provided with an opaque adhesive material applied to the filter (610).

[0180] For example, the foreign matter adsorption part (310) may be made of a material mixed with black ink and an adhesive material for light blocking, and in this respect, it may be expressed as a "light-blocking adsorption part," "adsorption mask," or "adsorption black mask."

[0181] The circuit board (800) may be provided with a terminal (814) that is electrically connected to a terminal (813) of an image sensor (810) by a wire (815).

[0182] A terminal (814) of the circuit board (800) may be disposed in a region of the circuit board (800) adjacent to the image sensor (1810). For example, the terminal (814) of the circuit board (800) may include a plurality of terminals disposed in a region of the circuit board (800) located around the image sensor (810).

[0183] The filter (610) and the image sensor (810) may be arranged to face each other in the optical axis direction, and the foreign matter adsorption part (310) may overlap with at least one of the terminal (813) of the image sensor (810), the terminal (814) of the circuit board (800), and / or the wire (814) in the optical axis direction.

[0184] The foreign matter adsorption portion (310) placed at the edge area of ​​the upper surface (62) of the filter (610) can serve to block unnecessary parts (e.g., reflected light) of the incident light passing through the lens module (400) and entering the image sensor (810) from entering the image sensor (810).

[0185] The wire (815) and terminals (813, 814) may be formed of a conductive material, such as gold, silver, copper, copper alloy, etc., and such conductive material may have the property of reflecting light.

[0186] That is, light passing through the filter (610) can be reflected by the image sensor (813), the terminal (814) of the circuit board (800), and the wire (815), and such reflected light can cause a momentary flash, i.e., a flare phenomenon, and such a flare phenomenon can distort the image formed on the image sensor (810) or degrade the image quality.

[0187] Since the foreign matter adsorption part (310) is positioned so as to overlap at least a portion with the terminals (813, 814) and / or the wire (815) in the direction of the optical axis, it can block light passing through the lens module (400) that is directed toward the terminal (813) of the image sensor (810), the terminal (814) of the circuit board (800), or / and the wire (815). As a result, the occurrence of the flare phenomenon described above can be prevented, and the image formed on the image sensor (810) can be prevented from being distorted or the image quality degraded.

[0188] A recess (21A) or a groove may be provided in the inner corner of the foreign matter adsorption part (310) corresponding to the corner of the filter (610).

[0189] The recess (21A) may be formed on the inner surface or at the corner of the inner end of the foreign matter adsorption part (310). The recess (21A) may be formed on at least two of the four inner corners of the foreign matter adsorption part (310).

[0190] The recess (21A) may be formed to avoid the corner of the active area of ​​the image sensor (810) when viewed from the optical axis direction or from above. For example, the recess (21A) may have a shape such as an arc, a curve, or a polygon when viewed from the first direction or from above.

[0191] For active alignment of the lens module (400) and the image sensor (810), the auto active alignment equipment must detect the position (or coordinates) on the xy-plane of the active area (811) of the image sensor (810). For example, the auto active alignment equipment can determine the position (or coordinates) on the xy-plane of the active area (811) of the image sensor (810) by recognizing the four corners of the active area (811) of the image sensor (810).

[0192] In the case where the foreign matter adsorption part (310) has a light blocking function, by providing a recessed part (21A) in the foreign matter adsorption part (310), the auto active alignment equipment can detect the four corners of the active area (811) of the image sensor (810) accurately, easily, and smoothly.

[0193] If the foreign matter adsorption part (310) does not have a light blocking function, the foreign matter adsorption part (310) may not have a recessed part (21A).

[0194] FIG. 12 is an exploded perspective view of an image sensor unit (350-1) according to another embodiment, and FIG. 13 is a partially enlarged cross-sectional view of the image sensor unit (350-1) of FIG. 12.

[0195] Referring to FIGS. 12 and 13, the image sensor unit (350-1) may further include a light-blocking member (320) disposed between the foreign matter adsorption unit (310-1) and the filter (610).

[0196] In FIG. 5, the foreign matter adsorption part (310) is placed or attached to the upper surface of the filter, but in FIG. 12, the light-blocking member (320) can be placed or attached to the upper surface of the filter (610).

[0197] The light-blocking member (320) may have the same shape as the foreign matter adsorption part (310) described in FIG. 5, and the description of the arrangement and shape of the foreign matter adsorption part (310) may be applied equally to the light-blocking member (320).

[0198] For example, the light-blocking member (320) may have an opening, such as a through hole, provided at a position corresponding to the image sensor (810).

[0199] The light-blocking member (320) may be placed in the edge area of ​​the upper surface (62) of the filter (610). For example, the light-blocking member (320) may be coupled or attached to the edge area of ​​the upper surface (62) of the filter (610).

[0200] For example, the light-blocking member (320) may have a polygonal shape, for example, a square shape. For example, the light-blocking member (320) may have a closed curve or ring shape, but is not limited thereto. For example, the light-blocking member (320) may have a closed curve shape with a polygonal, for example, square-shaped opening, but is not limited thereto.

[0201] The light-blocking member (320) may be formed symmetrically with respect to the filter (610) along each side of the upper surface (62) of the filter (610). For example, the light-blocking member (320) may be formed symmetrically left and right or symmetrically up and down with respect to the filter (610).

[0202] For example, the light-blocking member (320) may be formed to have a constant width on each side of the upper surface of the filter (610), but is not limited thereto.

[0203] The side or outer surface of the light-blocking member (320) may be in the same plane as the side (61) of the filter (610) and / or the side of the foreign matter adsorption part (310-1). For example, the side or outer surface of the light-blocking member (320) may be in contact with the side of the filter (610) and / or the side of the foreign matter adsorption part (310-1), but is not limited thereto. In other embodiments, the side of the light-blocking member (320) may not be in the same plane as the side (61) of the filter (610) and / or the side of the foreign matter adsorption part (310-1), and the side of the light-blocking member (320) may be spaced apart from the side (61) of the filter (610) (or the side of the foreign matter adsorption part (310-1)) or the corner where the side of the filter (610) and the upper surface of the filter (610) meet.

[0204] For example, the light-blocking member (320) may be spaced apart from the inner surface (12) of the seating portion (500) of the holder (600).

[0205] The light-blocking member (320) may overlap at least a portion with the bottom surface (11) of the mounting portion (500) in the direction of the optical axis.

[0206] Additionally, the light-blocking member (320) may overlap with at least a portion of the image sensor (810) in the direction of the optical axis. Additionally, the light-blocking member (320) may not overlap with the active area (811) of the image sensor (810) in the direction of the optical axis. For example, the light-blocking member (320) may be attached to or fixed to the filter in the form of a film or double-sided tape.

[0207] The light-blocking member (320) serves to block light. The light-blocking member (320) can block unnecessary parts (e.g., reflected light) of the light passing through the lens module (400) and incident on the image sensor (810) from being incident on the image sensor (810), thereby preventing flare phenomena and preventing distortion of the image formed on the image sensor (810) or degradation of image quality. The reflected light may be the same as described in the foreign matter adsorption part (310) of FIG. 10b.

[0208] The light-blocking member (320) may be made of a light-blocking material. For example, the light-blocking member may include black ink.

[0209] The light-blocking member (320) may have a recess (31). The description of the recess (21A) of the foreign matter adsorption member (310) may be applied to or analogously applied to the recess (31A) of the light-blocking member (320).

[0210] The foreign matter adsorption part (310-1) can be placed on the light-blocking member (320).

[0211] The description of the foreign matter adsorption part (310) according to the embodiments of FIGS. 1 to 10b may be applied to or mutatis mutandis to the foreign matter adsorption part (310-1) of FIGS. 12 and 13.

[0212] For example, the foreign matter adsorption part (310) of FIGS. 12 and FIGS. 13 may have only an adsorption function without a light-blocking function, but is not limited thereto, and may have a light-blocking function in other embodiments.

[0213] In the direction of the optical axis, the light-blocking member (320) can overlap with the foreign matter adsorption part (310-1).

[0214] The width (W1) of the light-blocking member (320) may be the same as the width of the foreign matter adsorption part (310-1).

[0215] At this time, the width (W1) of the light-blocking member (320) may be the length from the inner surface (or inner side) to the outer surface (or outer side) of the light-blocking member (320). Additionally, the width of the foreign matter adsorption part (310-1) may be the length from the inner surface (or inner side) to the outer surface (or outer side) of the foreign matter adsorption part (310-1).

[0216] FIG. 14 shows another embodiment (310-2) of the foreign matter adsorption part (310-1) of FIG. 13.

[0217] Referring to FIG. 14, at least a portion of the foreign matter adsorption portion (310-2) may be placed on the upper surface of the filter (610) adjacent to the inner circumference (or inner side) of the light-blocking member (320).

[0218] The width (W2) of the foreign matter adsorption part (310-2) may be larger than the width (W1) of the light-blocking member (320). Since W2 > W1, the embodiment can improve the foreign matter adsorption performance.

[0219] For example, the foreign matter adsorption portion (310-2) may include a first portion that overlaps with the light-blocking member (320) in the direction of the optical axis and a second portion that does not overlap with the light-blocking member (320) in the direction of the optical axis.

[0220] FIG. 15 shows another embodiment (310-3) of the foreign matter adsorption part (310-1) of FIG. 13.

[0221] Referring to FIG. 15, the foreign matter adsorption portion (310-3) may expose a portion of the upper surface of the light-shielding member (320). For example, a portion of the upper surface of the light-shielding member (320) adjacent to the inner circumference (or inner side) of the light-shielding member (320) may be exposed from the foreign matter adsorption portion (310-3).

[0222] The width (W3) of the foreign matter adsorption part (310-2) may be smaller than the width (W1) of the light-blocking member (320) (W3 <W1).

[0223] FIG. 16 shows another embodiment (310A) of the foreign matter adsorption part (310) of FIG. 8.

[0226] For example, the adsorption portions (P1 to P4) may include a first portion (85A) positioned at one corner of the upper surface of the filter (610).

[0227] Additionally, the adsorption portions (P1 to P4) may include a second portion (85B1) that extends toward one of the other two corners of the upper surface of the filter (610) adjacent to the corner of the upper surface of the filter (610).

[0228] Additionally, the adsorption portions (P1 to P4) may include a third portion (85B2) that extends toward the other one of the other two corners of the upper surface of the filter (610) adjacent to any of the corners of the upper surface of the filter (610).

[0229] For example, the adsorption portions (P1 to P4) may include at least one bent portion. For example, the adsorption portions (P1 to P4) may be in the shape of an "ㄱ", but are not limited thereto.

[0230] The adsorption portions (P1 to P4) may be provided with a recessed portion (21A1). The recessed portion (21A1) may be formed at the inner corner of the foreign matter adsorption portions (P1 to P4). The function of the aforementioned recessed portion (21A) may be applied to or analogously applied to the recessed portion (21A1) of FIG. 16.

[0235] For example, the area (or size) of each of the first adsorption parts (e.g., Q1) may be smaller than the area (or size) of each of the second adsorption parts (e.g., Qn). This is to enable the function of the aforementioned depressions (21A).

[0236] In another embodiment, the area (or size) of each of the first adsorption parts may be the same as the area (or size) of each of the second adsorption parts (e.g., Qn).

[0237] The foreign matter adsorption parts (310A, 310B) of FIGS. 16 and 17 are variations of the foreign matter adsorption part (310) and differ only in shape; therefore, the description of the foreign matter adsorption part (310), excluding the shape, can be applied to or mutatis mutandis to the foreign matter adsorption parts (310A, 310B) of FIGS. 16 and 17.

[0238] FIG. 18 shows another embodiment (310C) of the foreign matter adsorption part (310-1) of FIG. 12 and FIG. 13.

[0239] Referring to FIG. 18, the foreign matter adsorption part (310C) may include a plurality of adsorption parts (R1 to R4) spaced apart from each other on the upper surface of the light-shielding member (320).

[0240] Each of the plurality of adsorption parts (R1 to R4) can be placed at any one of the corresponding corners of the upper surface of the light-blocking member (320).

[0241] For example, the adsorption portions (R1 to R4) may include a first portion (86A) disposed at one corner of the upper surface of the light-blocking member (320).

[0242] Additionally, the adsorption portions (R1 to R4) may include a second portion (86B1) that extends toward one of the other two corners of the upper surface of the light-shielding member (320) adjacent to the corner of the upper surface of the light-shielding member (320).

[0243] Additionally, the adsorption portions (R1 to R4) may include a third portion (86B2) that extends toward the other one of the other two corners of the upper surface of the light-shielding member (320) adjacent to any one of the corners of the upper surface of the light-shielding member (320).

[0244] For example, the adsorption portions (R1 to R4) may include at least one bent portion. For example, the adsorption portions (R1 to R4) may be in the shape of an "L", but are not limited thereto.

[0245] The adsorption portions (R1 to R4) may be provided with a recessed portion (31A1). The recessed portion (31A1) may be formed at the inner corner of the foreign matter adsorption portions (R1 to R4). The function of the aforementioned recessed portion (31A) may be applied to or mutatis mutandis to the recessed portion (31A1) of FIG. 18.

[0250] For example, the area (or size) of each of the first adsorption parts (e.g., S1) may be smaller than the area (or size) of each of the second adsorption parts (e.g., Sn). This is to enable the function of the aforementioned depressions (31A).

[0251] In another embodiment, the area (or size) of each of the first adsorption parts (e.g., S1) may be the same as the area (or size) of each of the second adsorption parts (e.g., Qn).

[0252] The foreign matter adsorption parts (310C, 310D) of FIGS. 18 and 19 are variations of the foreign matter adsorption part (310-1) and differ only in shape; therefore, except for the shape, the description of the foreign matter adsorption part (310-1) can be applied or mutatis mutandis to the foreign matter adsorption parts (310C, 310D) of FIGS. 18 and 19.
