ABSTRACT:
A chip resistor having a highly accurately adjusted low resistance value is obtained. The chip resistor having a vertically three-layered structure is obtained by forming a first electrode1A by printing paste for an electrode on an insulating substrate5and drying it, a resistor layer3by printing paste for a resistor on the first electrode1A and drying it, a second electrode1B by printing paste for an electrode on the resistor layer3and the insulating substrate5and baking it. Trimming is applied to the thus fabricated chip resistor so as to adjust a resistance value to a given value.
