A light receiving element 5 arranged to be optically coupled to the light emitting element 4 but electrically separated from the light emitting element 4; and a light that commonly covers the light emitting element 4 and the light receiving element 15. In a photocoupler having a transparent and soft optical coupling resin layer 8 and a hard sealing resin layer 9 covering the optical coupling resin layer 8, the light reflecting member is harder than the optical coupling resin layer 8. 1
1 to the optical coupling resin layer 8 and the sealing resin layer 9
The light reflecting member 11 is arranged so as to cover the area from the light emitting element 4 to the light receiving element 5, and the light reflectance of the light reflecting member 11 is set to be the same as that of the sealing resin layer 9. A photocoupler that is characterized by being larger than that. (2) A utility model registration claim characterized in that the light blocking performance of the sealing resin layer 9 for light in a wavelength range to which the light receiving element 5 responds is greater than that of the light reflecting member 11. The photocoupler described in item 1. (3) The photocoupler according to claim 2, wherein the light reflecting member 11 is made of a white material, and the sealing resin layer 9 is made of a black resin. (4) The light reflecting member 11 includes a plate portion 11a that covers the light emitting element 4 and the light receiving element 5, and leg portions 11b for determining the distance between the plate portion 11a and the support member. A photocoupler according to claim 1, 2, or 3 of the utility model registration claim, which comprises:
