According to one embodiment, an isolator includes: a first semiconductor chip; a second semiconductor chip; a first wiring board including a first surface provided thereon with the first semiconductor chip; a second wiring board including a second surface provided thereon with the second semiconductor chip, the second wiring board being spaced apart from the first wiring board; a third wiring board spaced apart from each of the first and second wiring boards; a first coil on the first surface; a second coil on the second surface; a third coil on a third surface of the third wiring board, the third surface facing the first and second surfaces, the third coil facing the first coil; a fourth coil on the third surface, facing the second coil, and electrically coupled to the third coil; and an insulator provided between the first to fourth coils.

Isolator

According to one embodiment, a semiconductor module includes a first semiconductor element, a second semiconductor element, a first light emitting element and a second light emitting element. The first semiconductor element is provided with a first light receiving circuit and a first output circuit. The second semiconductor element is provided with a second light receiving circuit and a second output circuit. The first light emitting element is electrically connected to the second output circuit and mounted on the first semiconductor element such that first light emitted from the first light emitting element is received by the first light receiving circuit. The second light emitting element is electrically connected to the first output circuit and mounted on the second semiconductor element such that second light emitted from the second light emitting element is received by the second light receiving circuit.
