Patent ID: 7877868

Claim:
A method of fabricating a circuit configuration assembly, comprising: disposing an adhering sheet between a heat radiating member and a circuit configuration member and a case main body; adhering the circuit configuration member to an adhering face of the heat radiating member by thermally pressing the adhering sheet disposed therebetween; adhering the case main body to the adhering face of the heat radiating member by thermally pressing the adhering sheet disposed therebetween, thereby forming a space, around the circuit configuration member, defined by an inner side face of the case main body and the heat radiating member; filling the space with a waterproof resin in a liquid state so that a connecting part of the circuit configuration member is sealed by the waterproof resin; and forming a waterproof layer by lowering a fluidity of the waterproof resin, wherein the circuit configuration member includes a circuit board and one or more parts attached to the circuit board, at least a portion of the adhering sheet directly contacts a portion of the circuit board and the heat radiating member, and the portion of the circuit board is adhered to the adhering face of the heat radiating member by thermally pressing the adhering sheet disposed therebetween.
