Abstract: In order to provide a chip resistor which has wide and flat terminal electrodes in its front surface and which has high connection reliability between front electrodes and the terminal electrodes, a chip resistor according to the present invention includes: an insulating substrate 1 shaped like a cuboid; a pair of front electrodes 2 provided on lengthwise opposite edge portions of a front surface of the insulating substrate 1; a resistor body 3 provided between the front electrodes 2; an insulating protection layer 4 covering entire surfaces of the front electrodes 2 and the resistor body 3; and a pair of terminal electrodes 5 provided on lengthwise opposite end surfaces of the insulating substrate 1. The chip resistor is configured such that the front electrodes 2 sandwiched between the insulating substrate 1 and the protection layer 4 are exposed from widthwise end surfaces and the lengthwise end surfaces of the insulating substrate 1, and the terminal electrodes 5 wrap around the widthwise opposite end surfaces of the insulating substrate 1 to be thereby connected to the exposed portions of the front electrodes 2.
