Certain embodiments provide a method for producing a solid-state imaging device including the steps of forming an interconnection layer, forming a passivation film, forming a resist layer, forming a plurality of protruding portions and an opening, and forming an electrode pad. In the step of forming the interconnection layer, the interconnection layer is formed on the surface of the semiconductor substrate having a photodiode. In the step of forming the resist layer, the resist layer is formed on the passivation film such that the resist layer has a plurality of first openings above the photodiode and has a second opening above the interconnection of the interconnection layer. In the step of forming the plurality of protruding portions and the opening, the plurality of protruding portions and the opening are formed by etching the passivation film via the resist layer.
