PROBLEM TO BE SOLVED: To provide a lens holding device capable of improving positioning accuracy in terms of fixing a lens in a lens barrel. SOLUTION: The lens holding device is equipped with the lens barrel 12 having an aperture part 14 on one side in an optical axis J direction, and the lens 11 press-fit in the lens barrel 12 from the aperture part 14. The lens barrel 12 has a tapered inner peripheral surface 16, a holding surface 17 and a positioning part 18. The lens 11 is press-fit in the lens barrel 12 in a direction where the inside diameter of the tapered inner peripheral surface 16 becomes larger from the aperture part 14, and the lens 11 is stopped by the abutting surface 18A of the positioning part 18 and also the holding surface 17 abuts on the outer peripheral surface 11A of the lens 11 so as to hold the lens 11 at a predetermined position.
