Abstract
An optical waveguide integrated light receiving element includes an optical waveguide () arranged on a side of a second contact layer () opposite to a side where a light absorption layer () is arranged, having a waveguide direction parallel to a plane of the light absorption layer (), and optically coupled with the second contact layer (). The second contact layer () has, in a planar view, a size of an area smaller than that of the light absorption layer () and arranged inside the light absorption layer ().
