Abstract:
1. A photodiode array comprising: a semiconductor substrate of a first conductive type, wherein a plurality of photodiodes are formed in array form on a surface onto which light to be detected is made incident; and the semiconductor substrate has penetrating wirings, which pass through from the light-incident surface side to a back surface side, formed for the photodiodes and a protruding portion, formed of an insulating resin and having a predetermined height, is formed at regions of the light-incident surface side at which the photodiodes are not formed, wherein each of the plurality of photodiodes is formed so as to add an impurity to a surface of one side of the semiconductor substrate to form a plurality of impurity diffusion layers of a second conductive type, and wherein the first conductive type is opposite to the second conductive type.
