NOVELTY - An insulation film-containing stainless steel foil has insulation film (2) including layer (21) and layer (22), formed on stainless steel foil (1) as a base material. The layer (21) has heat resistance higher than that of layer (22). The layer (21) is metal oxide film, and has thickness of 0.1-0.4 micrometer (when metal oxide is zirconia), or 0.1-0.2 micrometer (when metal oxide is other metal oxide). The layer (22) is methyl group-containing silica-type film, and has thickness of 0.5-2 micrometer. The insulating film-containing stainless steel foil has leakage current of less than 10-5 A/cm2.    USE - Insulation film-containing stainless steel foil is used for copper-indium-gallium selenide-type solar cell (claimed), electronic paper, organic electroluminescent display device and illumination apparatus.    ADVANTAGE - The insulation film-containing stainless steel foil has excellent heat resistance and crack resistance.    DETAILED DESCRIPTION - An insulation film-containing stainless steel foil has insulation film including layer (21) and layer (22), formed on stainless steel foil which is a base material. The layer (21) has heat resistance higher than that of layer (22). The layer (21) is metal oxide film, and has thickness of 0.1-0.4 micrometer (when the metal oxide is zirconia), or 0.1-0.2 micrometer (when metal oxide is other metal oxide). The layer (22) is methyl group-containing silica-type film, and has thickness of 0.5-2 micrometer. The weight decreasing rate at the time of heating the insulating film at 500 degree C with respect to the time of heating the insulating at 100 degree C is less than 1%. The insulating film-containing stainless steel foil has leakage current of less than 10-5 A/cm2 when the voltage of 100 V is applied to an area of 3x 3 cm of the insulating film-containing stainless steel foil. An INDEPENDENT CLAIM is included for manufacture of insulation film-containing stainless steel foil.    DESCRIPTION OF DRAWING(S) - The drawing shows schematic view of insulation film-containing stainless steel foil.    Stainless steel foil (1)    Insulating film (2)    Layers (21,22)
