An electronic device capable of balancing both light transmitting and receiving performance and mounting reliability is provided. The electronic device includes an element (light receiving element), a transparent layer, and a sealing resin layer. The element is, for example, a semiconductor element and has an optically functional region having an optical function (for example, light receiving or light emission) on one face. The transparent layer is located on the optically functional region, directly comes in contact with the one face of the light receiving element, and is optically transparent. The sealing resin layer seals sides of the transparent layer and one face of the light receiving element, does not coat an upper face of the transparent layer, and is mixed with filler that improves rigidity. |
