PROBLEM TO BE SOLVED: To provide an inexpensive and high heat-resistant wiring circuit board that can be manufactured using inexpensive materials by a simple manufacturing method. SOLUTION: After a wiring circuit 11 is formed on an insulating layer 10 through which a glass solution of hardened type glass permeates by metal paste by printing, the insulating layer with the wiring circuit formed is impregnated with the glass solution of the hardened type glass. Then, it is hardened to form glass, and a wiring circuit board with excellent heat resistance is manufactured. In the glass-impregnated wiring circuit board, there are two or more layers of insulating layers with the wiring board formed. COPYRIGHT: (C)2003,JPO |
