A method for adjusting an optical axis of an imaging optical system is provided. The imaging optical system includes: a first lens element; a right-angle prism; and a lens group, and is incorporated in a lens barrel including: a first holding member positioning and fixing the first lens and the right-angle prism; and a second holding member incorporating the lens group. The method includes: when assembling the first holding member and the second holding member, positioning the first holding member relative to the second holding member; making inspection light incident into the first lens; and changing a relative position of the first holding member to the second holding member so that an image obtained from the inspection light takes a reference position, so as to coincide an optical axis of the subject light emerged from the right-angle prism with an optical axis of the lens group.
