An annular condensing lens for a parallel light beam, comprising a rotating body obtained by rotating the optical axis side of the cut plane about the straight line. (2) The rotating body obtained by rotating around the straight line has a two-dimensional qualitative distribution as it is before the rotation becomes a three-dimensional qualitative distribution as described in claim 1 of the utility model registration claim. Annular condenser lens for parallel light flux. (3) The annular condensing lens for parallel light flux according to claim 1, wherein the basic lens is a convex lens. (4) The annular condensing lens for parallel light flux according to claim 1, wherein the basic lens is a rod lens.
