Improve the focusing accuracy of the imaging element and the objective lens. With the objective lens unit frame that holds the objective lens (L1, L2) and (2), fitted on the outside of the objective lens unit frame, the image pickup device holding frame which holds the image pickup device 4 and (3), the objective lens a cross-sectional shape of the fitting portion (10) and at least the image pickup device holding frame of the units outside the frame surface, and the cross-sectional shape of the fitting portion (11) with at least an objective lens unit frame of the image pickup device holding frame in the surface different, when fitted and the objective lens unit frame and the image pickup device holding frame, in these mating portion, a contact portion where the outer surface and the image pickup device holding frame on the inner surface of the objective lens unit frame comes into contact, And a gap portion (21) in which the outer surface of the objective lens unit frame and the inner surface of the image pickup element holding frame do not come in contact with each other, and the objective lens unit frame and the image pickup device Providing an endoscopic image pickup device and the child holding frame is fixed by adhesive.撮像素子と対物レンズとのピント調整精度を向上させる。 対物レンズ(L1,L2)を保持する対物レンズユニット枠(2)と、対物レンズユニット枠の外側に嵌合し、撮像素子4を保持する撮像素子保持枠(3)と、を備え、対物レンズユニット枠外表面のうち少なくとも撮像素子保持枠との嵌合部分(10)の横断面形状と、撮像素子保持枠内表面のうち少なくとも対物レンズユニット枠との嵌合部分(11)の横断面形状とが異なり、対物レンズユニット枠と撮像素子保持枠とが嵌合したときに、これらの嵌合部分において、対物レンズユニット枠の外表面と撮像素子保持枠の内表面とが接触する接触部分と、対物レンズユニット枠の外表面と撮像素子保持枠の内表面とが接触しない隙間部分(21)と、が形成され、隙間部分に充填された光硬化性接着剤により対物レンズユニット枠と撮像素子保持枠とが接着されて固定されている内視鏡用撮像装置を提供する。
