ABSTRACT:
An optically coupled semiconductor device according to the present invention comprises a mount electrode and a wire electrode which are formed on a top main face of the first wiring substrate, a light-emitting element is electrically connected to the mount electrode and the wire electrode, a first electrode pad and a second electrode pad which are provided on the top main face of the second wiring substrate in such a manner as to sandwich the opening formed in the second wiring substrate, a photo-receptor element which is arranged in such a manner as to block the opening formed in the second wiring substrate and which is connected to the first electrode pad so as to face the light-emitting element, and a switching element which is connected to the second electrode pad so as to face the wire.
