[0054] ===First Embodiment===
[0055]
[0056] Figure 1A and Figure 1B It is an overall perspective view of the ferrule 1 of the first embodiment. figure 2 It is a cutaway perspective view of the ferrule 1 of the first embodiment. image 3 It is a six-sided view of the ferrule 1 of the first embodiment.
[0057] In the following description, each direction is defined as shown in the figure. That is, the direction of the optical fiber hole 12 is referred to as "front and rear direction", the side of the connection end surface 10A of the ferrule 1 is referred to as "front", and the opposite side is referred to as "rear". In addition, the thickness direction of the ferrule 1 is referred to as the "vertical direction", the opening side where the adhesive is filled into the adhesive filling portion 14 is referred to as the "upper direction", and the opposite side is referred to as the "lower direction". In addition, a direction perpendicular to the front-back direction an...

[0104] === Second Embodiment ===
[0105] The ferrule 1 of the second embodiment has a reflective portion 19 . Furthermore, an optical signal is transmitted via the reflector 19 .
[0106] Figure 8 It is a schematic sectional view of the ferrule 1 of the second embodiment. In addition, the same code|symbol is attached|subjected to the part of the same structure as 1st Embodiment, and description is abbreviate|omitted.
[0107] The ferrule 1 of the second embodiment is fixed on the photoelectric conversion module 30 via a bracket (not shown). For example, positioning pins (not shown) are formed on the lower surface of the ferrule 1, and by fitting the positioning pins into the positioning holes (not shown) of the bracket (not shown) bonded and fixed on the upper surface of the photoelectric conversion module 30, ), the ferrule 1 is positioned relative to the photoelectric conversion module 30 . Examples of the optical element 32 of the photoelectric conversion module 30 i...

[0112] ===Third Embodiment===
[0113]
[0114] Figure 9A , Figure 9B It is an overall perspective view of the ferrule 1 of the third embodiment. in addition, Figure 10 is a cutaway perspective view of the ferrule 1 of the third embodiment, Figure 11 It is a plan view of the ferrule 1 of the third embodiment. In addition, a schematic cross-sectional view of an optical connector to which the ferrule 1 according to the third embodiment is mounted and Figure 7 same.
[0115] In the following description, each direction is defined as shown in the figure. That is, the direction of the optical fiber hole 12 is referred to as "the front-rear direction". That is, the direction of the optical axis of the optical fiber 3 (see FIG. 16 ) inserted into the fiber hole 12 is the "front-rear direction". In this front-rear direction, the ferrule end surface 10A side is referred to as "front", and the opposite side is referred to as "rear". That is, the fiber end face side is "f...
