PROBLEM TO BE SOLVED: To improve image quality by reducing the deviation of the normal line of the light receiving surface in a solid-state imaging element from the optical axis of incident light even when adopting a package body and a lid body whose linear expansion coefficients do not match with each other. SOLUTION: A package body 3 in a recessed shape provided with an opening 3a houses the solid-state imaging device 2. A planar lid body 4 having prescribed light transmission characteristics is piled up on the opening 3a of the package body 3, its peripheral part is attached to the peripheral part 6 of the opening 3a in the package body 3, and the opening 3a is sealed. The shape in the plane view of the lid body 4 is a roughly n-angled shape (n is an integer≥3), and a chamfer 4a which is straight or circular arcuate in the plane view is formed at all the n pieces of corner parts of the lid body 4.
