Member having substrate with projecting portions at surface and light receiving layer of amorphous silicon
 A light-receiving member comprises a substrate having a large number of protruding portions on a surface thereof, each of said protruding portions having at a predetermined cut position a sectional shape comprising a main projection and a subprojection, the main projection and the subprojection overlapping each other, and a light-receiving layer of a multi-layer structure having a first layer comprising an amorphous material containing silicon atoms and germanium atoms and a second layer comprising an amorphous material containing silicon atoms and exhibiting photoconductivity provided on said substrate successively from the substrate side.
