Abstract
A plurality of holes are formed in a ferrule. The holes are at sites penetrated by the tips of optical fibers. An opening is formed in the upper surface of the ferrule and an internal housing section is exposed from the opening. The housing section is at a site at which an optical fiber holding member is housed. The optical fibers are held by the optical fiber holding member. The optical fibers are multi-core fibers. In other words, the optical fibers have a specified axis of symmetry in a cross-section vertical to the longitudinal direction of the optical fibers and have orientation relative to a rotation direction having the longitudinal direction as the axis thereof.
