Abstract
An electrode of a conductive material containing silver and a thick-film resistor of an electric resistive material containing cermet, which is electrically connected to the electrode, are formed on an electric insulating substrate by printing respectively. Then, the thick-film resistor is directly irradiated with a laser beam to be trimmed, and thereafter a protective film of an electric insulating material containing resin is formed on the insulating substrate by printing, to cover the electrode and the thick-film resistor.
