CHIP RESISTOR, JUMPER CHIP RESISTOR, AND ITS MANUFACTURING METHOD

PROBLEM TO BE SOLVED: To provide an excellently reliable chip resistor capable of preventing a characteristic defect caused by disconnection even if a diffusion reaction is generated in a part where a gold electrode is superimposed on a silver electrode. SOLUTION: The chip resistor includes a substrate 11, a pair of first upper surface electrodes 12 formed at both ends of the upper surface of the substrate 11, a pair of second upper surface electrodes 13 formed so as to be at least partially superimposed on the pair of first upper surface electrodes 12, and a resistor 14 arranged so as to be electrically connected to the pair of second upper surface electrodes 13. The pair of first upper surface electrodes 12 are composed of a conductor with gold as a main component, and the pair of second upper surface electrodes 13 are composed of conductors adopting silver as main components and containing scaly silver powder.
