Claims

[Scope of utility model registration request]

A first groove holding an optical fiber and an optical waveguide having a predetermined pattern are arranged in a state in which the optical axis of the optical fiber held in the first groove and the optical axis of the optical waveguide coincide with each other. an end of the optical fiber and an end of the optical waveguide are provided on a common substrate so as to face each other; a second groove for receiving a guide pin is provided on the substrate; an optical circuit in which the guide pin is received in the groove of No. 2;
