Patent ID: 7786842

Claim:
A chip resistor comprising: an insulating substrate including a main surface and two end surfaces spaced from each other in a longitudinal direction of the main surface; a main upper electrode formed on the main surface of the insulating substrate; a resistor film including a main resistor portion and an end, the main resistor portion being held in contact with the main surface of the insulating substrate, the end overlapping an upper surface of the main upper electrode; an auxiliary upper electrode which is formed on the main upper electrode and longer than the main upper electrode in a width direction which is perpendicular to the longitudinal direction; an undercoat including a main portion covering the resistor film and an extension connected to the main portion, the extension extending on the auxiliary upper electrode and being shorter than the auxiliary upper electrode and longer than the main upper electrode in the width direction; an overcoat formed on the main portion of the undercoat; and an additional electrode formed on an upper surface of the extension of the undercoat, the additional electrode being longer than the extension in the width direction to partially come into contact with the auxiliary upper electrode, part of the additional electrode overlapping an upper surface of an end of the overcoat.
