Claims

[Scope of utility model registration request]

Reinforcing FR is applied to the surface of the metal plating layer formed on the surface of the convex mandrel with a parabolic curve.
A light condensing plate characterized in that the metal plating layer is attached to the inner peripheral surface of the reinforcing FRP structure by laminating P structures and removing the mandrel.
