In a module (51) including circuit elements, a plurality of wires (12), which are generally two-dimensionally formed, are multi-layered via electrically insulating material (11), which comprises a mixture including at least filler and electrically insulating resin. One or more circuit elements are electrically connected to the wires, and at least a part of those circuit elements is embedded in the electrically insulating material. The module (51) further includes a heat sink member (13) that has a higher thermal conductivity than the electrically insulating material, and that, when viewed from the direction of multi-layering the wires, overlaps with a circuit element (14), which is one of those circuit elements, exhibiting the highest temperature rise at least in the module.
