ABSTRACT:
A chip resistor includes a resistor element of a rectangular solid made of an alloy composed of high-resistant metal and low-resistant metal. The resistor has connection terminal electrodes disposed at the ends of the resistor element that are spaced longitudinally of the rectangular solid. The resistance of the chip resistor is lowered without incurring an increase in the temperature coefficient of resistance and the weight. A plating layer is formed on the resistor element, where the plating element is made of pure metal having a lower resistance that that of the alloy constituting the resistor element.
