ABSTRACT:
An electronic circuit module comprises a case, first and second substrates disposed in the case on opposite inner walls with a gap therebetween and, a flexible film having a circuit pattern thereon and attached at a part to the first substrate and attached at another part to the second substrate. A first group of electronic components including a heat-generating component are mounted on the film part attached to the first substrate. A second group of electronic components including a low-heat-resistive component are mounted on the film part attached to the second substrate. The gap between the first and second substrates is filled with a resin layer, preferably a foam resin layer, having a low heat conductivity so as to prevent a heat transfer from the heat-generating part to the low-heat-resistive part.
