The invention relates to a chip resistor which is used as a circuit part for various electric apparatuses. The object of the invention is to realize a low resistance and a low TCR, and also high accuracy and high reliability. In order to achieve the object, a chip resistor is configured so as to have: a substrate; a resistance layer which is formed on at least one face of the substrate and which is made of a copper nickel alloy; upper-face electrode layers which make surface contact with the upper faces of both the end portions of the resistance layer; and end-face electrodes which are formed so as to cover the upper-face electrode layers. Since the bonding between the resistance layer and the upper-face electrode layers is conducted by metal-to-metal bonding, particularly, impurities which may affect the Properties do not exist in the interface. As a result, it is possible to realize a chip resistor which is excellent in heat resistance, and which has a low resistance and a low TCR.
