ABSTRACT:
A chip resistor (1) includes a chip substrate (2) a mutually separated terminal electrodes (3, 4) formed on the upper surface of the substrate (2), and a meandering resistor film (5) formed between the two terminal electrodes (3, 4). Each of the terminal electrodes (3, 4) includes an inner edge (3a, 4a) extending diagonally from one side surface (2a) toward the other side surface (2b) of the chip substrate (2). Each of the inner edges (3a, 4a) has a portion closer to the resistor film (5) that is electrically connected to a narrow portion (7, 8) formed integral with the resistor film (5). The narrow portion extends outward from an end (5a, 5b) of the resistor film (5).
