Patent ID: 7782174

Claim:
A chip resistor comprising: a ceramic substrate shaped like a rectangular parallelepiped; a pair of bank-raising foundation sections that are made mainly of glass and positioned on both longitudinal ends of the lower surface of the ceramic substrate; a pair of first electrode layers that are provided in regions covering at least parts of the bank-raising foundation sections and positioned at a predetermined distance from each other; a resistive element that is made mainly of copper and positioned in a region bridging the first electrode layers; a pair of second electrode layers that are positioned in regions covering the first electrode layers; an insulating protective layer that covers the resistive element exposed between the second electrode layers; a pair of end-face electrodes that are positioned on both longitudinal end faces of the ceramic substrate with the lower ends closely attached to the second electrode layers; and a plating layer that covers the second electrode layers and the end-face electrodes; wherein the plating layer is soldered to a wiring pattern on a circuit board with the first and second electrode layers positioned on the wiring pattern to mount the chip resistor on the circuit board.
