Abstract
A substratea cathodeand an anodeare stored in a space demarcated by a casingand the space is evacuated. The cathodeand the anodeare provided on the same surface of a substratehaving electric insulation, and have a comb-tooth shape so as to be mutually engaged. Therefore, the area of the part in which the cathodeand the anodeapproach each other becomes larger, and thereby photoelectrons discharged from the cathodethrough the incidence of ultraviolet rays are transmitted in the vacuum, and are favorably collected in the anode
