PROBLEM TO BE SOLVED: To freely select the shape of a curved surface and requested performance by letting age hardening type liquid state dielectric band flow into the mold of a three-dimensional curved surface to harden it and shaving off unwanted parts. SOLUTION: On a piller-shaped three-dimensional curved surface metal mold 11 for which an upper surface is formed into the shape to be applied to one side of a substrate, a conductor layer a1 is formed by depositing a copper foil film, for example. Next, a side wall metal mold 12 is fitted to the metal mold 11 along its peripheral surface, and age hardening type liquid state dielectric A islet flow into it and hardened. When this age hardening type liquid state dielectric A is completely hardened, the side wall metal mold 12 is drawn, the unwanted parts is shaven off by a three- dimensional cutting machine, and a dielectric layer a2 having dimensionally high precision is formed. Continuously, the side wall metal mold 12 is fitted again and on the upper surface of the dielectric layer a2, a dielectric layer a3 is formed by deposition, etc. Afterwards, by drawing the three-dimensional curved surface metal mold 11 and the side wall metal mold 12, a dielectric substrate in the shape of curved surface arranging the conductor layers a1 and a3 on the front side and rear side of the dielectric layer a2 can be provided. |
