A waveguide includes a core part, clad layer surrounding the core part about an optical axis of the core part, and an optical path conversion mirror formed at the end face of at least one of the core part or the clad layer. The optical path conversion mirror converts an optical path of a signal light. The shape of the end face of the core part and the shape of the end face of the clad layer are different in the optical path conversion mirror.
