Therefore, it is necessary to expose the optical fiber and the inner layer in a manner corresponding to the lengths of the first region, the second region, the fourth region, and the fifth region formed on the inner surface of the first pin body and the second pin body constituting the hybrid connector (1).

[0136] The optical fiber of the first optical cable (140) passes through the first region (111) and is drawn out of the first extraction hole (114).
