Abstract: A lens unit (LU) holding at least two lenses (4, 5) in a lens frame (1) adjacently in the optical axis direction and provided with positioning protrusions (2c, 2d) formed in correspondence with each of the two lenses (4, 5) in at least three separate locations in the peripheral direction of the lens frame (1), protruding from the inner surface of the lens frame (1) and contacting a peripheral surface of a corresponding lens to position the corresponding lens relative to the lens frame (1), an adhesive filling space (GSP1) formed between the peripheral surface of each of the two lenses (4, 5) and the inner surface of the lens frame (1) in overlap with the two lenses (4, 5), and an adhesive injection hole (1c) formed in the lens frame (1) in communication with the adhesive filling space (GSP1).
