- the block 59 has an end face 59d in which the opening of the through hole 29b is formed, and a tapered portion 63 is formed between the uneven portion 60 and the end face 59d.
- the tapered portion 63 has a C-shaped opening 63b on the end surface 59d.
- the tapered portion 63 is a portion that widens from the uneven portion 60 toward the end face 59d. Therefore, the area of the opening 63b when viewed along the first direction D1 is larger than the area of the uneven portion 60 when viewed along the first direction D1.
- the tapered portion 63 is defined by a pair of first inclined surfaces 63c and a second inclined surface 63d.
- the pair of first inclined surfaces 63c are inclined from each inner side surface 61 toward the end surface 59d in both the first direction D1 and the third direction D3.
- the second inclined surface 63d extends from the bottom surface 62 toward the end surface 59d and is inclined with respect to both the first direction D1 and the second direction D2. Since the second optical connector 52 is provided with the uneven portion 60 in which the tapered portion 63 is formed, the insertion of the first connector into the second optical connector 52 can be performed smoothly.
