Abstract

In a photodetecting device, a wiring boardis provided at the front surface side of a photodetecting elementso that a first bonding pad regionformed on the front surface of the photodetecting elementis exposed, and second bonding padsB are formed, of the wiring board, in the region on a further inner side than first bonding padsA. Thereby, in the photodetecting device, a forming space for wire bonding can be located at the inside of the photodetecting element, so that the wiring boardand the photodetecting elementcan be made almost equal in size. As a result, in the photodetecting device, the area that the photodetecting elementoccupies relative to the photodetecting devicecan be sufficiently secured, and minimization of the non-sensitive region in the case of a buttable arrangement of the photodetecting deviceson a cold platecan be realized.
