Abstract
A semiconductor device includes an insulating member, a light-receiving element, a light-emitting element, a switching element, a metal reflection plate, a first resin member and a second resin member. The light-receiving element, the switching element and the metal reflection plate are provided on and arranged along a front surface of the insulating member. The switching element is electrically connected to the light-receiving element. The light-emitting element provided on the light-receiving element and optically coupled to the light-receiving element. The metal reflection plate is proximate to the light-receiving element. The first resin member covering the light-emitting element on the light-receiving element. The second resin member covering the light-receiving element, the light-emitting element, the first resin member, the switching element, and the metal reflection plate on the front surface of the insulating member.
