Abstract:
A ferrule structure includes: a ferrule body including a guide hole that accepts insertion of a guide pin, and a fiber hole that accepts insertion of an optical fiber and that is disposed in an opening surface of the ferrule body; and a lens plate including a guide hole that accepts insertion of the guide pin, a lens part, and an abutment surface that abuts an endface of the optical fiber. A recess is disposed in at least one of the ferrule body and the lens plate. A matching material filling gap, that is to be filled with a refractive index matching material, is formed with the recess, between the opening surface of the ferrule body and the abutment surface of the lens plate.
