PURPOSE:To facilirate the manufature of an accurate filmy circuit, by depositing a film circuit material, and thereafter forming or shaping a filmy circuit pattern by the projection of a laser light beam. CONSTITUTION:A thick filmy conductor paste is printed on an insulating alumina substrate 1 and burned. Thus a thick conductor film 2 of silver palladium is formed. A thick filmy resistor paste is printed and burned and a thick film resistor 3 is formed. Unnecessary parts of the thick conductor film 2 and the thick film resistor 3 are burned away by a laser light beam, and a thick film conductor inductor 2' and a thick film resistor 3' are shaped.
