A rewiring region is provided in a region other than a pixel region on a front face (pixel formation surface) FA of an imaging element. A mold part is formed around the imaging element other than on the front face FA. Rewiring layers that connect an external terminal and a pad provided in the rewiring region are formed via insulating layers on a side of the pixel formation surface of the imaging element and the mold part. Therefore, connection to a substrate can be made possible even if the spacing between the pads is narrowed, a mounting surface of an imaging device is also on the side of the pixel formation surface, and reduction in size and height can be achieved.
