PROBLEM TO BE SOLVED: To make the outside diameter of a lens with a lens barrel smaller, also, to enhance the coupling strength of the lens barrel and the lens, and also, to easily and inexpensively manufacture the lens with a lens barrel, besides, to enable easily mounting the lens with a lens barrel on a sheet-like mount member, and also, to make the lens with a lens barrel usable as a zoom lens component, as for the lens with a lens barrel and a method for manufacturing the lens with a lens barrel. SOLUTION: The lens with a lens barrel 28 is constituted of a lens barrel member 2 where an annular swelling part 2c is formed on the outer periphery of an intermediate part, an annular recessed groove 2d is formed in the inner peripheral surface and through-holes 2a and 2b communicating between the inside and the outside are arranged in at least one or more places in the swelling part 2c, and a plastic lens 26 obtained by injection-molding in the lens barrel member 2 while fitting the outer peripheral edge part of the lens to the annular recessed groove 2d and partly protruding the outer peripheral edge part of the lens into the through-holes 2a and 2b, and the lens with a lens barrel manufacturing method using an injection molding die device 3 is introduced.
