A solid-state image device, comprising:
- an image region which has a plurality of optical-electrical conversion portions two-dimensionally arranged and a plurality of vertical CCD registers which are placed adjacent to said optical-electrical conversion portions arranged in line in a vertical direction, said vertical CCD register transferring electrical charge signals converted by said optical-electrical conversion portions toward the vertical direction;
- a horizontal CCD register which is coupled to said vertical CCD registers at one end and which transfers the electrical charge signals toward a horizontal direction;
- a first light shielding film which covers said image region except for said optical-electrical conversion portions and which is formed by a first material;
- and
- a second light shielding film which covers said horizontal CCD register and which is formed by a second material;
- the first material being different from the second material.
