摘要：
A forming method of a thermal insulation film includes a first step of forming an anode oxidation coating film on an aluminum-based wall surface, the anode oxidation coating film including micro-pores each having a diameter of micrometer-scale and nano-pores each having a diameter of nanometer-scale; and a second step of coating a surface of the anode oxidation coating film with a sealant containing filler to seal at least part of the micro-pores and the nano-pores by the sealant so as to form the thermal insulation film.
