In a lens system assembling method, the spacing between two mutually opposing lenses are set more accurately. The method includes the steps of: holding a first lens with a lens holding member, with the opposing lens face of the first lens being brought into close contact with a first receiving face of a spacing jig, and a lens receiving face of the lens holding member being brought into close contact with a second receiving face of the spacing jig; removing the spacing jig from the first lens and the lens holding member holding the first lens; and setting the spacing between the mutually opposing first and second lenses at a predetermined distance by abutting the second lens to the lens receiving face of the lens holding member such that the opposing lens face of the second lens is brought into close contact with the lens receiving face.
