PROBLEM TO BE SOLVED: To provide a photosensor capable of simplifying molding processes with a resin of a light projection element, a light receiving element, and a light emitting element relating to an operation display lamp.SOLUTION: A photosensor includes: a light projection element; a light projection sealing part; a light receiving element; a light receiving sealing part; a circuit part; and a circuit sealing part. The light projection sealing part seals the light projection element. The light receiving sealing part seals the light receiving element. The circuit part includes a light emitting element for operation display. The circuit sealing part seals the circuit part. The circuit sealing part includes an operation display part at a position facing the light emitting element. The light projection sealing part, the light receiving sealing part, and the circuit sealing part are connected through a conductive lead frame. The light projection sealing part, the light receiving sealing part, and the circuit sealing part are formed by a resin made of the same material containing a light diffusion agent. |
