A light receiving device according to the present disclosure includes an element portion in which at least a first contact layer, a light absorbing layer, and a second contact layer are laminated in this order on a substrate. The substrate and the element portion are covered with a first insulating portion made of, for example, a polymer material. Regarding the substrate surface, a separation portion formed by a second insulating portion perpendicularly to the substrate surface is provided between an element region including an element portion of the light receiving device and a pad region including a pad that electrically and mechanically connects to the outside of the element. Even if the pad in the pad region or the vicinity thereof is damaged by external force, the moisture resistance of the second insulating portion keeps the deterioration of the moisture resistance due to the damage within the pad region.
A light receiving device including an element portion in which at least a first contact layer, a light absorbing layer, and a second contact layer are laminated in this order on a substrate, comprising:
