Abstract
A connector with built-in bent optical fibers includes an optical fiber array including a plurality of bent optical fibers each having a bent portion and a linear portion formed integrally with the bent portion, a ferrule having a plurality of positioning mechanisms that align end portions of the plurality of bent optical fibers, and a resin portion disposed at an outer periphery of the bent portion. The resin portion is filled in the ferrule. The bent portion has a bending angle of 85°-150°. When the bent portion of one bent optical fiber is divided into a plurality of regions along a longitudinal direction at 10°, a variation in bend radius among the plurality of regions excluding regions corresponding to 10° at both ends is 0.3 mm or less, an outer diameter of the bent portion of the bent optical fiber is smaller than an outer diameter of the linear portion.
