Abstract
A light-receiving package for flat-plate mounting which can make monitor reception sensitivity of an optical signal constant without increasing the size of a module. The light-receiving package for flat-plate mounting is provided with a first subassembly in which a photo diode is fixed to a front surface of a retaining holder, a back surface of the retaining holder is a flat surface capable of moving parallel on a plane parallel to a light-receiving surface of the photo diode and a second subassembly which has a rectangular U-shaped concave holder for retaining the retaining holder, and a flat-plate base disposed on a substrate and in which a surface of the flat-plate base that is mounted on the substrate is a flat surface capable of moving parallel to a substrate surface, the rectangular U-shaped concave holder and the flat-plate base are fixed, at least one of surfaces of the concave holder having a rectangular U-shape being a flat surface is a flat surface capable of moving parallel to the back surface of the retaining holder.
