Abstract

Abstract A coated layer type resistor device having a first resistor element and a second resistor element. The ratio between the resistances of the first and second resistor elements is selected to be greater than a predetermined ratio. The first resistor element is formed on an insulator substrate and consists of a resistor layer and end conductor electrodes at the ends of the resistor layer, while the second resistor element is formed on the substrate and consists of a resistor layer, end conductor electrodes, and a plurality of intermediate conductors. The distance between adjacent ones of the intermediate conductors and the distance between one of the end conductor electrodes and the adjacent intermediate conductor in the second resistor element is equal to the distance between the end conductor electrodes in the first resistor element, so that the temperature coefficient property of the resistance is equal in both the first and second resistor elements.
