In a lens module, a first lens barrel has opposing first and second ends and an optical axis. A glass lens is disposed in the first lens barrel, and a resin lens is disposed in the first lens barrel and is arranged to be closer to the second end than the glass lens is. A second lens barrel is disposed in the first lens barrel to surround the at least one resin lens. A holding mechanism applies pressing force to the at least one glass lens and the second lens barrel in a direction of the optical axis to perform pressure holding of the at least one glass lens and the second lens barrel in a direction of the optical axis. The holding mechanism holds the at least one resin lens while preventing the pressing force from being directly applied to the at least one resin lens.
