In a hybrid integrated circuit device of the present invention, leads are fixedly attached on the upper surface of a circuit board. The lead includes an island portion, a slope portion, and a lead portion. A transistor and a diode are mounted on the upper surface of the island portion. Electrodes provided on the upper surfaces of the transistor and the diode are connected to a bonding portion through a fine metal wire. The bonding portion of the lead is disposed at a higher position than the island portion. Thus, the fine metal wires connected to the bonding portion are separated from each other.

Circuit device and method of manufacturing the same

In a hybrid integrated circuit device, a circuit board on which an island portion of a lead is fixedly attached and a control board on which a control element and the like are mounted are disposed in an overlapping manner. The circuit board and the control board are integrally encapsulated with an encapsulating resin. A transistor disposed on an upper surface of the circuit board and a control element mounted on an upper surface of the control board are also covered by the encapsulating resin. Thus, a module in which an inverter circuit and a control circuit are integrally encapsulated with resin is provided.
