ABSTRACT:
A circuit board includes an insulative ceramic substrate, electrode portions and wiring portions formed on the ceramic substrate by selectively removing portions of a conductor layer plated on said ceramic substrate, a resistor layer formed on the ceramic substrate and connected to the electrode portions, and a pair of connecting thick film conductors for electrically connecting the thick film resistor and the conductor layer on both ends of the thick film resistor. The resistor layer includes a thick film resistor which is formed on the ceramic substrate. The conductor layer and the thick film resistor each have an end portion which is formed directly on the same connecting thick film conductor.
