ABSTRACT:
A chip resistor device includes an insulating chip substrate having a top surface formed with a resistor film which is covered by a protective coating. The top surface of the substrate is also formed with a pair of terminal electrodes provided at both ends of the chip substrate. Each of the terminal electrodes includes a main top electrode layer formed on the top surface of the chip substrate in electrical conduction with the resistor film, an auxiliary top electrode layer formed on the main top electrode layer, a side electrode layer formed on a corresponding end face of the chip substrate, and a plated metal electrode layer formed on the auxiliary top electrode layer and the side electrode layer. The auxiliary top electrode layer is formed with a cutout at which the plated metal electrode layer is held in direct contact with the main top electrode layer.
