PROBLEM TO BE SOLVED: To provide a lens barrel capable of highly accurately aligning lens optical axes of optical lenses in a lens barrel to which a plurality of optical lenses are attached. SOLUTION: In a lens barrel 10 to which a plurality of optical lenses are attached by press-fitting, a plurality of ribs (projections) to which the press-fitted optical lenses are abutted, are formed on a first lens holding surface for holding a first optical lens 1 and on a second lens holding surface for holding a second optical lens 2, respectively, and ribs 11a-11d formed on the first lens holding surface and ribs 12a-12d formed on the second lens holding surface are disposed while separating their positions in a peripheral direction.
