[0009] Hereinafter, embodiments of the technology according to the present disclosure will be described in detail with reference to the accompanying drawings.

[0010] First Embodiment FIGS. 1A and 1B are schematic perspective views showing the appearance of an electronic component 100 according to a first embodiment of the technology disclosed herein, viewed from different directions. FIGS. 2A and 2B are schematic perspective perspective views of the electronic component 100, viewed from different directions. For ease of explanation, FIGS. 1A, 1B, 2A, and 2B tentatively illustrate the X-axis, Y-axis, and Z-axis. Hereinafter, the direction of the arrow on each axis will be referred to as the + (plus) direction, and the opposite direction will be referred to as the − (minus) direction (the same applies to the other drawings). In this disclosure, the Z direction may be referred to as the first direction, the Y direction as the second direction, and the X direction as the third direction. Furthermore, a surface extending in the X and Y directions may be referred to as the XY plane, a surface extending in the X and Z directions as the XZ plane, and a surface extending in the Y and Z directions as the YZ plane.

[0011] The electronic component 100 according to the first embodiment includes a magnetic element 130 and metal frames 110 and 120 embedded in the magnetic element 130. The metal frames 110 and 120 are arranged in the X direction within the magnetic element 130. The coil axes of the coil conductors formed by the metal frames 110 and 120 are aligned in the Z direction. The magnetic element 130 may be made of a composite magnetic material in which a magnetic filler made of a high-permeability material such as ferrite or permalloy is solidified with a resin binder. This also applies to the magnetic element 230 used in the second embodiment, which will be described later. The magnetic element 130 has main surfaces 101 and 102 that are opposite each other and form an XY plane, side surfaces 103 and 104 that are opposite each other and form an XZ plane, and side surfaces 105 and 106 that are opposite each other and form a YZ plane. In this disclosure, the main surfaces 101 and 102 may be referred to as the first and second surfaces, respectively, and the side surfaces 103 to 106 may be referred to as the third to sixth surfaces, respectively.

[0012] The metal frames 110, 120 are members made of metal (e.g., copper (Cu)) and function as coil conductors. The metal frames 110, 120 may be made, for example, by punching a flat metal plate and then bending it. In this case, the thickness of the metal frames 110, 120 may be approximately constant throughout. Furthermore, the metal frames 110, 120 may each be an integral metal member with no joints or the like. The same applies to the metal frames 210, 220 used in the second embodiment described below.

[0013] As described above, the electronic component 100 according to this embodiment uses the metal frames 110 and 120 as coil conductors, and therefore has reduced DC resistance compared to coil conductors made of a plating film or the like. Therefore, the electronic component 100 according to this embodiment can be used, for example, as an inductor for a power supply circuit. Furthermore, because the metal frames 110 and 120 are arranged in the X direction, which is different from the coil axis direction, coupling between the coil conductor made of the metal frame 110 and the coil conductor made of the metal frame 120 is suppressed. Furthermore, because the metal frames 110 and 120 are arranged in the X direction, it is also possible to reduce the height in the Z direction.

[0014] 3A and 3B are schematic perspective views illustrating the structure of the metal frame 110 (120), showing the state as viewed from different directions. The metal frame 110 and the metal frame 120 may have the same structure.

[0015] The metal frame 110 has sections 111 and 112 extending parallel to the Y direction, a section 113 extending in the X direction and connecting the end of section 111 in the +Y direction with the end of section 112 in the +Y direction, a section 114 connected to the end of section 111 in the -Y direction, a section 115 connected to the end of section 112 in the -Y direction, and a section 116 protruding in the -Z direction from section 113. The XY surface of section 114 is exposed from the main surface 101 of the magnetic body 130, and the XZ surface of section 114 is exposed from the side surface 104 of the magnetic body 130. The XY surface of section 115 is exposed from the main surface 102 of the magnetic body 130, and the XZ surface of section 115 is exposed from the side surface 104 of the magnetic body 130. The XY surface of section 116 is exposed from the main surface 102 of the magnetic body 130.

[0016] The metal frame 120 has sections 121 and 122 extending parallel to the Y direction, a section 123 extending in the X direction and connecting the end of section 121 in the +Y direction with the end of section 122 in the +Y direction, a section 124 connected to the end of section 121 in the -Y direction, a section 125 connected to the end of section 122 in the -Y direction, and a section 126 protruding in the -Z direction from section 123. The XY surface of section 124 is exposed from the main surface 101 of the magnetic body 130, and the XZ surface of section 124 is exposed from the side surface 104 of the magnetic body 130. The XY surface of section 125 is exposed from the main surface 102 of the magnetic body 130, and the XZ surface of section 125 is exposed from the side surface 104 of the magnetic body 130. The XY surface of section 126 is exposed from the main surface 102 of the magnetic body 130.

[0017] The surface of section 114 exposed from main surface 101 of magnetic body 130 constitutes one terminal electrode of the coil conductor made of metal frame 110. The surface of section 115 exposed from main surface 102 of magnetic body 130 constitutes the other terminal electrode of the coil conductor made of metal frame 110. The surface of section 124 exposed from main surface 101 of magnetic body 130 constitutes one terminal electrode of the coil conductor made of metal frame 120. The surface of section 125 exposed from main surface 102 of magnetic body 130 constitutes the other terminal electrode of the coil conductor made of metal frame 120. In this embodiment, sections 111 to 113 of metal frame 110 are not exposed from magnetic body 130, and sections 121 to 123 of metal frame 120 are not exposed from magnetic body 130. In this way, the small surface areas of metal frames 110 and 120 exposed from magnetic body 130 make it possible to obtain high inductance.

[0018] The surfaces of sections 116, 126 exposed from main surface 102 of magnetic body 130 may be used as heat dissipation terminals. The wiring pattern connected to the heat dissipation terminals may terminate without being connected to power supply wiring, signal wiring, etc. The surfaces of sections 114, 124 exposed from main surface 101 of magnetic body 130 may form the same plane. The surfaces of sections 115, 116, 125, 126 exposed from main surface 102 of magnetic body 130 may form the same plane.

[0019] Section 114 of metal frame 110 has a flat portion 114A connected to section 111, a flat portion 114B exposed from main surface 101 of magnetic body 130, and a bent portion 114C located between flat portions 114A and 114B and bent at approximately 90 degrees. The YZ plane of section 111 and the YZ plane of flat portion 114A of section 114 may be the same plane. A notch 118 is provided in metal frame 110, which forms a space between section 111 and bent portion 114C of section 114. Providing such a notch 118 makes it easier to bend bent portion 114C of section 114.

[0020] Section 115 of metal frame 110 has a flat plate portion 115A connected to section 112, a flat plate portion 115B exposed from main surface 102 of magnetic base body 130, and a bent portion 115C located between flat plate portions 115A and 115B and bent at approximately 90 degrees. The YZ plane of section 112 and the YZ plane of flat plate portion 115A of section 115 may be the same plane. A notch 119 is provided in metal frame 110, which forms a space between section 112 and bent portion 115C of section 115. Providing this notch 119 makes it easier to bend bent portion 115C of section 115.

[0021] Section 124 of metal frame 120 has a flat portion 124A connected to section 121, a flat portion 124B exposed from main surface 101 of magnetic body 130, and a bent portion 124C located between flat portions 124A and 124B and bent at approximately 90 degrees. The YZ plane of section 121 and the YZ plane of flat portion 124A of section 124 may be the same plane. A notch 128 is provided in metal frame 120, which forms a space between section 121 and bent portion 124C of section 124. Providing such a notch 128 makes it easier to bend bent portion 124C of section 124.

[0022] Section 125 of metal frame 120 has a flat plate portion 125A connected to section 122, a flat plate portion 125B exposed from main surface 102 of magnetic base body 130, and a bent portion 125C located between flat plate portions 125A and 125B and bent at approximately 90 degrees. The YZ plane of section 122 and the YZ plane of flat plate portion 125A of section 125 may be the same plane. A notch 129 is provided in metal frame 120, which forms a space between section 122 and bent portion 125C of section 125. Providing such a notch 129 makes it easier to bend bent portion 125C of section 125.

[0023] When manufacturing electronic component 100 having such a configuration, metal frames 110, 120 are bent, and then metal frames 110, 120 are placed on a support body so that sections 115, 116 of metal frame 110 and sections 125, 126 of metal frame 120 are in contact with the surface of the support body, and then metal frames 110, 120 are embedded in magnetic base body 130. As a result, metal frames 110, 120 each contact the surface of the support body at two locations, allowing metal frames 110, 120 to be stably supported on the surface of the support body, facilitating the manufacture of electronic component 100. Furthermore, if the surfaces of section 115 and section 116 exposed from main surface 102 of magnetic base body 130 form the same plane, metal frame 110 can be more stably placed on the support body. Similarly, if the surfaces of sections 125 and 126 exposed from main surface 102 of magnetic body 130 form the same plane, metal frame 120 can be placed more stably on the support.

[0024] 4A and 4B are schematic perspective views showing the appearance of an electronic component 200 according to a second embodiment of the technology disclosed herein, viewed from different directions. Also, FIGS. 5A and 5B are schematic see-through perspective views of the electronic component 200, viewed from different directions.

[0025] Electronic component 200 according to the second embodiment includes magnetic body 230 and metal frames 210, 220 embedded in magnetic body 230. Metal frames 210, 220 are arranged in the X direction within magnetic body 230. The coil axes of coil conductors formed by metal frames 210, 220 are in the Z direction. Magnetic body 230 has main surfaces 201, 202 that are opposite each other and form an XY plane, side surfaces 203, 204 that are opposite each other and form an XZ plane, and side surfaces 205, 206 that are opposite each other and form a YZ plane.

[0026] In this embodiment, the folded metal frames 210, 220 are used as coil conductors, and therefore the electronic component 200 according to this embodiment can be used, for example, as an inductor for a power supply circuit. Furthermore, the metal frames 210, 220 are arranged in the X direction, which is different from the coil axis direction, so coupling between the coil conductors made of the metal frames 210 and 220 is suppressed. Moreover, because the metal frames 210, 220 are arranged in the X direction, it is also possible to reduce the height in the Z direction.

[0027] 6A and 6B are schematic perspective views illustrating the structure of the metal frame 210 (220), showing the state as viewed from different directions. The metal frame 210 and the metal frame 220 may have the same structure.

Since section 216 protruding in the -Z direction and section 217 protruding in the +Z direction are connected to section 213, the metal frame 210 maintains the same shape even when turned upside down. In other words, the metal frame 210 does not need to have directionality in the Z direction.

[0029] 6A and 6B, section 211 has a protruding portion 211A that protrudes in the −Z direction from a portion near the end in the −Y direction. Section 212 has a protruding portion 212A that protrudes in the +Z direction from a portion near the end in the −Y direction.

Since section 226 protruding in the -Z direction and section 227 protruding in the +Z direction are connected to section 223, the metal frame 220 maintains the same shape even when turned upside down. In other words, the metal frame 220 does not need to have any directionality in the Z direction.

The XY surface of section 226 is exposed from the main surface 202 of the magnetic element body 230. The XY surface of the section 227 is exposed from the main surface 201 of the magnetic body 230 .

[0038] The surface of flat plate portion 214B of section 214 exposed from main surface 201 of magnetic body 230 constitutes one terminal electrode of the coil conductor made of metal frame 210.

The surface of flat plate portion 224B of section 224 exposed from main surface 201 of magnetic body 230 constitutes one terminal electrode of the coil conductor made of metal frame 220. The surface of flat plate portion 225B of section 225 exposed from main surface 202 of magnetic body 230 constitutes the other terminal electrode of the coil conductor made of metal frame 220. In this embodiment, the large surface area of ​​metal frames 210, 220 exposed from magnetic body 230 makes it possible to obtain high heat dissipation properties.

[0039] The surfaces of sections 213 (flat plate portion 213A), 216, 217, 223 (flat plate portion 223A), 226, and 227 exposed from magnetic body 230 may be used as a heat dissipation terminal. The surface of protruding portion 211A of section 211 exposed from main surface 202 of magnetic body 230 may be used as one terminal electrode of a coil conductor made of metal frame 210, or may be used as a heat dissipation terminal. The surface of protruding portion 212A of section 212 exposed from main surface 201 of magnetic body 230 may be used as the other terminal electrode of a coil conductor made of metal frame 210, or may be used as a heat dissipation terminal. The surface of protruding portion 221A of section 221 exposed from main surface 202 of magnetic body 230 may be used as one terminal electrode of a coil conductor made of metal frame 220, or may be used as a heat dissipation terminal. The surface of the protruding portion 222A of the section 222 exposed from the main surface 201 of the magnetic body 230 may be used as the other terminal electrode of the coil conductor made of the metal frame 220, or may be used as a heat dissipation terminal.

[0041] When manufacturing electronic component 200 having such a configuration, metal frames 210 and 220 are bent, and then metal frames 210 and 220 are placed on a support body so that sections 211 (protrusion 211A), 215 (flat plate section 215B), and 216 of metal frame 210 and sections 221 (protrusion 221A), 225 (flat plate section 225B), and 226 of metal frame 220 are in contact with the surface of the support body, and metal frames 210 and 220 are embedded in magnetic base body 230. Alternatively, after bending the metal frames 210 and 220, the metal frames 210 and 220 may be placed on the support body so that the sections 212 (protruding portion 212A), 214 (flat portion 214B), and 217 of the metal frame 210 and the sections 222 (protruding portion 222A), 224 (flat portion 224B), and 227 of the metal frame 220 are in contact with the surface of the support body, and then the metal frames 210 and 220 may be embedded in the magnetic base body 230. This allows the metal frames 210 and 220 to be in contact with the surface of the support body at three locations, making it possible to stably support the metal frames 210 and 220 on the surface of the support body, facilitating the manufacture of the electronic component 200. Furthermore, if the surfaces of the sections 211, 215, and 216 exposed from the main surface 202 of the magnetic base body 230 form the same plane, the metal frame 210 can be more stably placed on the support body. Similarly, if the surfaces of the sections 221, 225, and 226 exposed from the main surface 202 of the magnetic body 230 form the same plane, the metal frame 220 can be placed more stably on the support.

[0048] In the electronic component, the second section of the first metal frame may include a second protrusion that protrudes in the first direction opposite the first protrusion, and an end of the second protrusion may be exposed from the first surface of the magnetic body. In this way, when the first metal frame is embedded in the magnetic body, the second protrusion is brought into contact with the surface of the support, thereby making it possible to more stably support the first metal frame.

[0049] In the electronic component, the magnetic body may further have a fourth surface perpendicular to the first and second surfaces, and a portion of the fourth section of the first metal frame may be exposed from the first and fourth surfaces of the magnetic body, and a portion of the fifth section of the first metal frame may be exposed from the second and fourth surfaces of the magnetic body, thereby enabling heat to be dissipated from the fourth surface side of the magnetic body.

[0050] In the electronic component described above, the fourth section of the first metal frame includes a first plate portion connected to the first section, a second plate portion exposed from the first surface of the magnetic body, and a bent portion located between the first and second plate portions and connecting the first and second plate portions, and the first metal frame may be provided with a notch to form a space between the first section and the bent portion of the fourth section, which facilitates bending the bent portion.

[0051] The electronic component further includes a second metal frame embedded in the magnetic base body, the first metal frame and the second metal frame being arranged in a third direction perpendicular to the first and second directions, the second metal frame including seventh and eighth sections extending parallel to the second direction, the seventh section of the second metal frame including a fifth end which is one end in the second direction and a sixth end which is the other end in the second direction, the eighth section of the second metal frame including a seventh end which is one end in the second direction and an eighth end which is the other end in the second direction, The metal frame of the seventh section further includes a ninth section connecting the fifth end of the seventh section and the seventh end of the eighth section, a tenth section connected to the sixth end of the seventh section, an eleventh section connected to the eighth end of the eighth section, and a twelfth section protruding from the ninth section, wherein a portion of the tenth section of the second metal frame may be exposed from the first surface of the magnetic body, a portion of the eleventh section of the second metal frame may be exposed from the second surface of the magnetic body, and a portion of the twelfth section of the second metal frame may be exposed from at least one of the first and second surfaces of the magnetic body. This makes it possible to configure an inductor array in which two metal frames are embedded in the magnetic body.
