Abstract: A thermal insulation structure for an electronic device of the present invention is a thermal insulation structure which thermally insulates between an electronic circuit unit and a heat generator formed with another component. In the thermal insulation structure, a partition wall for separating each space and formed of resin having electric insulation properties is provided between the electronic circuit unit and the heat generator. Also, the partition wall is formed by integrating the resin and a thermal insulation material having thermal conductivity lower than thermal conductivity of air so that the resin includes the thermal insulation material. Further, the partition wall is formed by insert-molding the thermal insulation material with the resin. Further, the resin having the electric insulation properties is thermoplastic resin, and a thermal insulation raw material of the thermal insulation material is silica xerogel.
