PROBLEM TO BE SOLVED: To provide a solid-state imaging element which can advantageously reduce its size and cost, while increasing the image quality of an imaging system. SOLUTION: In the solid-state imaging element for receiving the image light of a subject and obtaining a digital image, a light receiving surface 16 has a curved shape. When 2Y denotes the diagonal line length of the light-receiving surface 16, and D denotes displacement in the optical axis direction between the mid point of the diagonal line and the diagonal point of the light-receiving surface, the relation 0.001≤D/2Y≤0.15 is satisfied. This enables effective correction of a field curvature aberration and improvement of the image quality. Since additional special parts are not required, this becomes advantageous in size reduction and cost reduction realized. COPYRIGHT: (C)2006,JPO&NCIPI
