Endoscope imaging device and endoscope

An endoscope imaging device that acquires an image of an observation target, comprising:

• at least one movement group including a movable lens that is movable along an optical axis;
• a plurality of fixed groups including a fixed lens whose position is fixed with respect to the optical axis;
• a sensor that receives light which has passed through the movable lens of the movement group and the fixed lens of the fixed group and that images the observation target;
• a lens drive portion that moves the movement group along the optical axis;
• and
• a lens barrel body provided with the movement group, the fixed group, and the lens drive portion,
• wherein at least one of the plurality of fixed groups is an adjustment group,
• the adjustment group includes a cylindrical holding part inside which the fixed lens is provided, the holding part includes a grip part provided at one end part of the holding part and an end surface provided at the other end part opposite to the one end part in an optical axis direction, and the grip part includes a projecting portion or a recessed portion whose diameter changes with respect to a radial direction of the holding part, and
• the adjustment group is configured such that the end surface provided at the other end part of the holding part is disposed at a position spaced apart from the lens barrel body or the fixed group in the optical axis direction, and the grip part is disposed at a position spaced apart from the lens barrel body or the fixed group in the optical axis direction and protrudes from the lens barrel body or the fixed group, and a side surface of the holding part is fixed to the lens barrel body or the fixed group.
