Abstract
A member having an arbitrary shape having a closed curve can be easily subjected to laser processing within a short time. A lens and a laser processing apparatus equipped with the lens are for cutting a material to be cut into a member having an arbitrary shape having a closed curve and include a convex cylindrical lens which is molded to have a closed path so that a line that connects vertices of a cylindrical surface of the convex cylindrical lens has the same form as the arbitrary shape having the closed curve.
