Abstract
An electrical equipment casing includes a circuit board on which many electrical parts are mounted and a heat sink to which the circuit board is fixed. The heat sink is provided with a reactor housing dent that opens in a surface on which the circuit board is placed and radiator fins that reach a bottom portion of the reactor housing dent on a surface opposite to the surface on which the circuit board is placed at a position surrounding an outer circumference of the reactor housing dent. The reactor is housed in the reactor housing dent and a terminal thereof is electrically connected to the circuit board. This structure of the electrical equipment casing can contribute to an achievement of both of a size reduction of the overall casing and enhanced heat dissipation of the reactor.
