ABSTRACT:
In manufacturing a chip resistor by dividing a chip resistance substrate which includes an insulator, resistance film formed on a surface of the insulator, and a plurality of conductive strips disposed on the resistance film at fixed intervals, grooves are formed by removing a predetermined width of the resistance film including at least second prescribed severing lines. After forming the grooves, the chip resistance substrate is severed in longitudinal and lateral directions along first prescribed severing lines for dividing the conductive strips into two parts and the second prescribed severing lines perpendicular to the first prescribed severing lines so as to produce discrete chip resistors.
