An optical fiber array (1) including a V-groove substrate (4) having at least one V-groove (3) in which at least one optical fiber (2) is arranged and a fiber fix substrate (5) for fixing the optical fiber (2) arranged on the V-grooves (3) is disclosed. In the optical fiber array (1) according to the invention, one of the V-groove substrate (4) and the fiber fix substrate (5) has a concave portion into which the other substrate is arranged in such a manner that a bottom surface of the concave portion of the one substrate is connected to a bottom surface of the other substrate directly or via the optical fiber (2), and the concave portion has side (8-1,8-2) end walls whose thickness is thicker than that of a bottom portion in which the V-grooves (3) are formed. Moreover, side inner surfaces of the concave portion of the one substrate and side surfaces (8-1,8-2) of the other substrate have a taper shape extending gradually wider toward an opening of the concave portion. <IMAGE> |
