Abstract
A chip resistor includes a resistor element in the form of a chip, and at least two electrodes formed on the resistor element. The resistor element includes an upper surface, a lower surface, and two end surfaces extending between the upper and the lower surfaces and spaced from each other. The two electrodes are provided on the lower surface of the resistor element. Each of the end surfaces of the resistor element is formed with a conductor film integrally connected to a corresponding one of the electrodes. The conductor film is made of copper, for example, and is higher in solder-wettability than the resistor element.
