摘要： An optical fiber array includes a V-groove substrate for housing an uncovered glass fiber section formed at an end portion of an optical fiber contained therein. A lower covered section housing portion houses a covered section of the optical fiber and is formed to be deeper than the V-groove forming portion. An optical fiber is disposed so that the uncovered glass fiber section is housed in the V groove and the covered section is housed in the lower covered section housing portion. A lid substrate is composed of a glass fiber protective portion covering an upper surface of the uncovered glass fiber section and an upper covered section housing portion houses a covered section of the optical fiber. The upper covered section housing portion is formed to be deeper than the glass fiber protective portion and is disposed on the V-groove substrate. A resin is filled in the gaps among the V-groove substrate, the optical fiber, and the lid substrate and cured to give a unitary optical fiber array. The glass fiber protective portion has a fiber contact portion to bring the fiber contact portion into direct contact with the glass fiber section, and a non-contact portion which is not brought into direct contact with the glass fiber section of the optical fiber.
