The purpose of the present invention is to provide a cemented lens and a lens unit equipped with the cemented lens capable of preventing an air bubble from entering between lenses, the creation of gaps, or separation and eccentricity between lenses, and the leakage of adhesive to outside the lens. A projection (253) projecting toward the outer peripheral region (241) of a first lens and coming in contact with the outer peripheral region (241) is formed at the outer peripheral region (251) of a second lens in a cemented lens (10), and thus allows highly accurate control of the distance between the lens surface (240) of a first lens (24) and the lens surface (250) of a second lens (25). An annular recess (243) formed in the outer peripheral region (241) of the first lens extends circumferentially to surround the lens surface (240), and thus surplus adhesive (40) collects in the recess (243). |
