<P>PROBLEM TO BE SOLVED: To provide a light receiving element having high sensitivity with less cost increase for sensitivity increase, a manufacturing method of the same and an optical device. <P>SOLUTION: A light receiving element 10 comprises: a light receiving layer 3 lying on a semiconductor substrate 1, for receiving light; a contact layer 5 lying on the light receiving layer 3; and a pixel electrode 11 ohmic contacting the contact layer. A rear face of the semiconductor substrate functions as a light incident surface. The light receiving element further comprises a reaction prevention film 8 for preventing chemical reaction between the contact layer and the pixel electrode, which lies in a limited area between the contact layer and the pixel electrode. <P>COPYRIGHT: (C)2013,JPO&INPIT |
