<p>Converged laser beam are irradiated, at right angles, to the surface (50a) of a workpiece (50) 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 (51a) 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 (51) having the convexly curved surface is formed. <MATH></p> |
