ABSTRACT:
A chip resistor includes a chip substrate, a terminal electrode formed on an upper surface of the chip substrate in a region close to the respective end portions, and a resistant film formed in a zigzag-folded shape on the upper surface of the chip substrate between the terminal electrodes. An inner edge of at least one of the terminal electrodes includes a protrusion integrally formed so as to project from a portion close to a side edge of the chip substrate toward the resistant film, for achieving electrical connection between the resistant film and the protrusion. A side edge of the protrusion facing inward farther from the side edge of the chip substrate is inclined such that a front edge of the protrusion has a narrower width.
