Patent attributes
A circuit device comprises a circuit board and a plurality of leads each comprising an island portion, a bonding portion elevated from the island portion, and an oblique slope portion connecting the island portion and the bonding portion, and a plurality of circuit elements mounted on the island portions so as to be connected to corresponding bonding portions through wirings. Two leads are adapted to be connected to positive and negative electrodes of a direct-current power source, and yet another lead is an output lead adapted to output alternating-current power. One electrode provided on 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 another electrode provided on 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.
