Abstract
In a flat plate type thick film resistor, an insulation performance is improved by excluding the nonuniformity of potential distribution on a wiring plane, which is generated when electric current flows in a resistance wire. Simultaneously, generation of noise depending on potential distribution and variation of stray capacitance around a resistor is suppressed. When the resistance wire having a constant thickness and uniform resistivity, which is formed on an insulating substrate, is connected to a pair electrode conductors that face to each other, in the way that the resistance wire is repetitively bent to the alternate side in zigzags, a potential gradient on the wiring plane, which is generated when electric current flows in the resistance wire, is constant by properly selecting the line width, the bending angle, and the spacing between bending vertexes of a resistance wire.
