Abstract
A resistor has a structure including a resistor substrate that has paired electrodes and a resistive element formed on an insulating substrate, an insulating exterior material that covers at least the upper and the side surface of the resistor substrate, and harness electric wires that have one end parts connected to the respective electrodes, pass through the exterior material, and extend outside. The paired electrodes are formed on areas other than the end parts of the insulating substrate, and junctions of the end parts of the harness electric wires and the paired electrodes are at positions where creepage distance of insulation from the junctions to the bottom ends of the insulating substrate is a predetermined distance or longer. Such structure provides the resistor having a secured creepage distance of insulation between the conductor parts of the resistor and the metal case in which the resistor is installed.
