Abstract
An optical coupling device includes a light receiving element including a first output terminal and a second output terminal, a light emitting element provided on the light receiving element, a first switching element, a first electrode plate, and a sealing member. The first switching element includes a first main terminal connected to the first output terminal, a first control terminal connected to the second output terminal, and a second main terminal. An upper surface of the first electrode plate is connected to the second main terminal. The sealing member covers the light receiving element, the light emitting element, and the first switching element. A lower surface of the first electrode plate is exposed on a lower surface of the sealing member. The lower surface of the first electrode plate and the lower surface of the sealing member form the same plane.
