The purpose of the present invention is to improve the accuracy of focal adjustment of an image pickup element and objective lenses. Provided is an image pickup device for an endoscope, equipped with an objective lens unit frame (2) for retaining objective lenses (L1, L2), and an image pickup element retainer frame (3) that retains an image pickup element (4) and mates with the outside of the objective lens unit frame. The cross-sectional shape of at least a mated section (10) that is the section of the objective lens unit frame outer surface that mates with the image pickup element retainer frame, differs from the cross-sectional shape of at least a mated section (11) that is the section of the image pickup element retainer frame inner surface that mates with the objective lens unit frame. When the objective lens unit frame and the image pickup element retainer frame are mated, there are formed in these mated sections a contacting section in which the outer surface of the objective lens unit frame and the inner surface of the image pickup element retainer frame are in contact, and a gap section (21) in which the outer surface of the objective lens unit frame and the inner surface of the image pickup element retainer frame are not in contact. The objective lens unit frame and the image pickup element retainer frame are bonded and secured by a photocurable adhesive that is packed into the gap section.La présente invention vise à améliorer la précision de réglage focal d'un élément de capture d'image et d'objectifs.
