Abstract:
1. An electronic control device, comprising: a circuit board accommodated in a casing and having mounted thereon electronic components including at least one heat-generating element; and a heat dissipation member having thermal conductivity and intervening between said heat-generating element or said circuit board and an inner surface of said casing or a surface of a pedestal thermally bonded to said casing, to provide thermal coupling between said heat-generating element and said casing, wherein said heat dissipation member is made of a polymeric material having fluidity and has two surfaces, one of which is in direct contact with said heat-generating element or said circuit board; and a film which prevents physical shifting of said heat dissipation member is disposed between said heat dissipation member and the inner surface of said casing or the surface of said pedestal, said film being chemically bonded to said heat dissipation member and said casing or said pedestal.
