Abstract
A heat-shielding film structure comprises a first and a second heat-shielding film. The first heat-shielding film is a heat-shielding film formed on a surface of a component that is formed from an Al alloy with an Al purity of less than 99.0% as a base material. The second heat-shielding film is a heat-shielding film formed on the surface of the first heat-shielding film. The second heat-shielding film is obtained by anodizing treatment of Al foil with an Al purity equal to or larger than 99.0%. The first heat-shielding film has a porous structure. The second heat-shielding film has a porous alumina on its surface. The first heat-shielding film and the porous alumina have a lower heat conductivity and a lower heat capacity per unit volume than the base material.
