    • A heat resistant black coating film which is capable of making the surface of optical members to be low reflection property and black property, a black light shading plate having a resin film using the same as a base substrate, and a diaphragm, a diaphragm device for light intensity adjustment and a shutter using the same, and heat resistant light shading tape. They are provided by a black coating film (A), where a titanium oxide film containing titanium and oxygen as main components, and having an oxygen content of from 0.7 to 1.4, as atomicity ratio O/Ti, is formed on an opaque or translucent substrate, characterized in that the titanium oxide film takes a constitution of fine columnar crystals assembled, where the longitudinal direction of the crystal extends in a film thickness direction, has protrusions at the film surface, and has a film thickness of equal to or thicker than 50 nm; and a black light shading plate, wherein the metallic light shading film (B), having a film thickness of equal to or thicker than 40 nm, is formed onto at least one surface of the substrate, and still more the black coating film (A) is laminated and formed on the surface of the metallic light shading film (B), or the like.
