Abstract
The invention is to provide a chip resistor suitable for lowering an initial resistance value. A chip resistoraccording to the present invention is provided with: an insulating substrate; a pair of front electrodeswhich are provided on a front surface of the insulating substrateso as to face each other with a predetermined interval therebetween; a resistive elementwhich is provided so as to bridge the front electrodes; a pair of auxiliary electrodeswhich are provided so as to cover the front electrodesand overlap end portions of the resistive element; and the like. The chip resistoris configured such that: the front electrodesare formed of a material which contains 1 to 5 wt % Pd and the balance Ag; and the auxiliary electrodesare formed of a material which contains 15 to 30 wt % Pd and a metal material (e.g. Au) lower in resistivity than Pd and the balance Ag.
