Abstract:
1. A ferrule for receiving an optical waveguide having a substantially rectangular cross-section shape, the ferrule comprising: a first end and a second end opposite to the first end; an insertion opening to which the optical waveguide is inserted, the insertion opening being disposed on the first end; and a positioning portion which positions said optical waveguide to an axial center of said insertion opening, wherein: the positioning portion includes a groove having a rectangular cross-section shape, the groove has an inclined portion in which a width of the rectangular cross-section shape of the groove gradually decreases as the inclined portion approaches to the second end so that an end of the optical waveguide abuts to the inclined portion and the inclined portion restricts the optical waveguide not to protrude beyond the second end when inserted, and an end of the inclined portion is disposed on the second end.
