Abstract

An imaging device (10, 102, 103) includes: a lens barrel (30) holding at least one optical element; a light-receiving circuit (50, 502) that at least has an image sensor (52, 522) and a drive substrate (51); and a welding structure in which the lens barrel and the optical element are joined by welding, in a state where a positional relationship between the image sensor and the optical element optically positioned is maintained, wherein the welding structure has an intermediate holder (54, 543) where a contact part (54d, 543d) on a lens barrel side that comes into contact with a contact portion (32a) of the lens barrel and a contact part (51a, 522a) on a light-receiving circuit side that comes into contact with a contact portion of the light-receiving circuit are provided; a welded part on the lens barrel side that is hardened after the contact portion of the lens barrel or the contact part on the lens barrel side is softened, where the contact portion of the lens barrel and the contact part on the lens barrel side are fixed; and a welded part on the light-receiving circuit side that is hardened after the contact portion of the light-receiving circuit or the contact part on the light-receiving circuit side is softened, where the contact portion of the light-receiving circuit and the contact part on the light-receiving circuit side are fixed.
