PROBLEM TO BE SOLVED: To improve the yield of an optical unit.SOLUTION: An optical unit 13 includes an optical system 16, a lens frame 15, and a fixing part 21. The optical system 16 includes a plurality of optical elements 22 to 26. The lens frame 15 is formed so that an opening on an object side is smaller than the outermost edge of an optical element 22 nearest to the object side in the optical system 16. The lens frame 15 is formed so that the opening on an imaging side is larger than the outermost edge of the optical element 26 nearest to the imaging side in the optical system 16. The lens frame 15 stores the optical system 16 inside. The fixing part 21 fixes the optical system 16 in the opening on the imaging side, in such a state that the optical system 16 is stored from the opening on the imaging side of the lens frame 15. |
