Summary:PROBLEM TO BE SOLVED: To fix a lens with high accuracy, and to efficiently absorb thermal expansion of the lens. SOLUTION: This lens unit includes a holder, the lens, and a rotationally symmetric lens holding part fixed inside the holder. The lens holding part suspends the lens in an optical axis direction of the lens inside the holder to make an optical axis and a central axis of the holder accord, and the thermal expansion in a radial direction of the lens is absorbed by shear strain.
