Abstract
A pair of upper electrode layers,, connected to resistor layer,, is formed with a gold system electro-conductive material containing glass frit on the side portion towards the edge of the upper surface of substrate,. The adhesive strength of which electrode layer to the substrate,is strong enough and the electrode layer withstands a thermal stress and a corrosive environment. A resistor thus manufactured maintains its superior electrical characteristics with a high operational reliability even in the harsh operating environment where there is a thermal amplitude lasting for a long term, in a corrosive atmosphere, etc.
