Abstract:
1. A heat release device for use with a multilayer board that has an inner layer serving as a power layer, comprising: a heat release member thermally and electrically connected to the power layer; a heat release board having a heat release layer and a shield layer electrically insulated from each other, the heat release layer being thermally and electrically connected to the heat release member, the shield layer serving to shield against electromagnetic noise radiated from the heat release layer, the shield layer being electrically insulated from the heat release member connected to the heat release layer; an electrically conductive member electrically connected to the shield layer and a grounded component; wherein the shield layer is provided between an electric component in the multilayer board and the heat release layer; and an insulator through which the heat release layer is thermally connected to the electrically conductive member.
