Abstract: A chip resistor having a predetermined resistance value is manufactured by the following method. A resistive element is provided on an upper surface of an insulating substrate. The resistive element includes a wide portion, a first narrow portion extending from the wide portion, and a part extending from the wide portion, the first narrow portion has a smaller width than the wide portion. First and second electrodes are provided on the upper surface of the insulating substrate. The first electrode is located away from the wide portion. The first electrode contacts the first narrow portion. The first electrode overlaps the first narrow portion when viewed from above. The second electrode contacts the part of the resistive element. The second electrode overlaps the part of the resistive element when viewed from above. A distance between the narrow portion and the wide portion is determined so as to cause a resistance value between the first and second electrodes to be the predetermined resistance value. This method improves the precision of the resistance value of the chip resistor.
