Abstract

By providing an end portion of a radiation plate located on and near an end portion of an insulator sheet, to which a lead frame extends, at a position away from the end portion of the insulator sheet inside of the insulator sheet in a plane direction of the insulator sheet, it is possible to secure a creeping distance between the lead frame and the radiation plate without decreasing a lead frame area on which components can be actually mounted.
