    • PROBLEM TO BE SOLVED: To provide a heat-resistant and light-shielding film which is used as an optical equipment component such as shutter blade or diaphragm blade of lens shutter, or the like, of digital camera and digital video camera, and diaphragm blade of light quantity adjusting diaphragm device of a projector and is superior in light-shielding properties, heat-resistant properties, sliding properties, low brilliant property and electrically conductive property, to provide a manufacturing method of the heat-resistant and light-shielding film, and to provide the diaphragm or the light quantity adjusting device that uses the heat-resistant and light shielding film. SOLUTION: The heat-resistant and light-shielding film comprises a resin film base material (A), having heat resistance of at least 200°C; an Ni-type metal film (B), having a film thickness of at least 50 nm formed on one surface or both surfaces of the resin film base material (A) by a sputtering method; and a low-reflexivity Ni-type oxide film (C) formed on the Ni-type metal film (B) by the sputtering method, wherein the surface roughness falls in the range of 0.1 to 0.7 μm (arithmetic mean height Ra).
