Abstract
Converged laser beam are irradiated, at right angles, to the surface of a workpiece which is made of glass and supported in a horizontal posture, so that the surface of the workpiece is locally heated and melted. The surface of the workpiece is formed into a convexly curved surface under the effect of surface tension occurrable to the glass material at the time the surface of the workpiece is melted. By hardening the workpiece, a micro lens having the convexly curved surface is formed.
