Abstract
An electrical device according to the present invention has a case (), a metallic heat sink plate () disposed an opening portion (OP) of the case and a circuit board () arranged on the heat sink plate. The heat sink plate () is interposed between a capacitor () and the circuit board () so that the circuit board () is separated from the capacitor () by not only the resinous case () but also the metallic heat sink plate (). Thus, electromagnetic space noise generated from the capacitor () is shielded or reduced by the metallic heat sink plate () whereby a malfunction of the circuit board () is prevented from occurring due to electromagnetic space noise generated from the capacitor ().
