<p>[PROBLEMS] To provide a chip resistor which hardly causes defective mounting and easily promotes resistance reduction. [MEANS FOR SOLVING PROBLEMS] A chip resistor (1) includes a ceramic substrate (2) having on its lower surface, a pair of augmenting groundwork portions (3) positioned at both ends in the longitudinal direction, a pair of first electrode layers (4) arranged at a predetermined interval and covering at least a part of the augmenting groundwork portions (3), a resistor (5) bridging the first electrode layers (4) and formed by a copper/nickel alloy as a main component, a pair of second electrode layers (6) covering the pair of the first electrode layers (4), and an insulating protection layer (7) covering the resistor (5). Moreover, at the both end faces of longitudinal direction of the ceramic substrate (2), end face electrodes (9) are provided. The second electrode layers (6) and the end face electrodes (9) are coated by plating layers (10-13). The chip resistor (1) is face-down mounted by placing the both electrode layers (4, 6) on a wiring pattern (21) of a circuit substrate (20).</p> |
