Abstract
A circuit assembly includes a circuit board on which a coil is mounted, a heat sink, and a heat spreading plate that is separate from this heat sink. A first insulating adhesive layer is interposed between the circuit board and the heat spreading plate, and the heat spreading plate and the heat sink are fixed by a first fixing hole for a heat sink and a bolt. Accordingly, warping of the circuit board is suppressed.
