An optical fiber array is provided in which an optical fiber tip end is housed in a holding member ( 2 ). The holding member ( 2 ) consists of a substrate ( 3 ) and a cover plate ( 5 ). The substrate ( 3 ) forms a sectional V shaped housing groove ( 4 ) for housing the optical fiber ( 1 ) on a top face. The cover plate ( 5 ) covers the top face of the substrate ( 3 ). An adhesive is filled between the substrate ( 3 ) and the cover plate ( 5 ) which fixes optical fiber ( 1 ) in the housing groove. A distance Y between the substrate ( 3 ) and the cover plate ( 5 ) is L / 6<=Y<=L, with Y being the thickness of the adhesive layer and L being a distance from a contact point (P) between the housed optical fiber ( 1 ) and the housing groove ( 4 ) to the cover plate ( 5 ). In this manner, even under severe environmental conditions, a release or delamination of the holding member ( 2 ) is not likely to occur, and good optical coupling characteristics can be maintained.
