The present disclosure includes: a base plate having a shape of a sheet; a relay plate having a shape of a sheet; a terminal member; and an electronic component joined to one surface of the base plate. The base plate, the relay plate, and the terminal member are electrically conductive members and arranged on a same plane with gaps between the electrically conductive members. The electronic component and one surface of the relay plate are connected to each other by a bonding wire. The one surface of the relay plate and one surface of the terminal member are connected to each other by a bonding wire.

A semiconductor package includes: a package board including a plurality of connection pads; a semiconductor chip including a first surface and a plurality of bonding pads, wherein the first surface of the semiconductor chip contacts a first surface of the package board, and wherein the plurality of bonding pads are respectively connected to the plurality of connection pads; and a thermal fuse circuit connected between a sensing connection pad of the plurality of connection pads and a sensing bonding pad of the plurality of bonding pads, and configured to open between the sensing connection pad and the sensing bonding pad when an internal temperature of the thermal fuse circuit is greater than or equal to a cutoff temperature of the thermal fuse circuit.
