Abstract: This endoscope imaging device is to improve focus adjustment accuracy between an imaging element and an objective lens. This endoscope imaging device has an objective lens unit frame holding objective lenses, and an imaging element supporting frame fitted onto an outer side of the objective lens unit and holding an imaging element. The lateral cross-sectional shape of a fitted portion of an outer surface of the objective lens unit frame and the lateral cross-sectional shape of a fitted portion of an inner surface of the imaging element supporting frame are different, and in the fitted portions, a contact portion where said two frames come into contact, and a gap portion where said two frames do not come into contact are formed, and also the objective lens unit frame and the imaging element supporting frame are cemented by a photosetting glue filled in the gap portion.
