Member having substrate with protruding surface portions and light receiving layer with amorphous silicon matrix
 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, a second layer comprising an amorphous material containing silicon atoms and exhibiting photoconductivity and a surface layer having reflection preventive function provided on the substrate successively from the substrate side.
