Optical device, optical device apparatus, camera module, and optical device manufacturing method

摘要

An optical device includes an optical element, a transparent member arranged on the optical element, and a transparent resin adhesive for causing the transparent member to adhere and be fixed onto a circuit formation face of the optical element. The optical device includes a light detecting region having a plurality of micro lenses, a peripheral circuit region formed in the outer peripheral part of the light detecting region, and an electrode region formed at the outer peripheral part of the peripheral circuit region. A roughed region in a saw-toothed shape in section is formed in part of a face of the transparent member which adheres to the optical element, the part being overlapped with the outer peripheral part of the light detecting region as viewed in plan.
