Abstract
A light-receiving detection device comprises: an optical device; a light-receiving surface for receiving light transmitted through the optical device; and a holder for holding the optical device with side surfaces and mounting surfaces which intersect with respective side surfaces and to which the light-receiving surface is bonded. Each of said side surface has a concavity (concavities) having at least two inner surfaces, at least one of which is tapered, that is, broadened at the lower portion. The adhesive to bond the light-receiving surface to the holder is applied in the cavity to flow down to the contact area of the light-receiving surface and the holder.
