Abstract
An optical path changing member is assembled at ends of optical fibers and placed to face a substrate including an optical input/output terminal having optical axes inclined with respect to optical axes of the ends. The optical path changing member is made of a transparent material and includes a member body having a reflection surface for optically connecting the ends to the optical input/output terminal. The member body has optical fiber insertion holes and an end placement portion to which the insertion holes are open and in which the end faces of the optical fibers are placed. The reflection surface is formed so that light entering from the end faces of the optical fibers into the member body will be internally reflected toward the optical input/output terminal in the member body. The end placement portion is filled with an adhesive by which the ends are fixed to the member body.
