Claim:
1. A circuit device comprising: a circuit board; a plurality of leads, each of the leads comprising an island portion attached to an upper surface of the circuit board, a bonding portion elevated from the island portion, and a slope portion extending obliquely so as to connect the island portion and the bonding portion; a plurality of circuit elements mounted on the island portions so as to be connected to corresponding bonding portions through wirings; wherein one of the leads is a first input lead adapted to be connected to a positive electrode side of a direct-current power source, another of the leads is a second input lead adapted to be connected to a negative electrode side of the direct-current power source, and yet another of the leads is an output lead through which alternating-current power obtained by converting direct-current power inputted through the first input lead and the second input lead is adapted to be outputted; an electrode provided on an upper surface of a transistor mounted on an island portion of the second input lead is connected to a bonding portion of the output lead through a wiring; and an electrode provided on an upper surface of a transistor mounted on an island portion of the output lead is connected to a bonding portion of the first input lead through a wiring.
