<p><P>PROBLEM TO BE SOLVED: To positively apply highly accurate trimming adjustment with low resistance in which two probes for conduction contact a single top surface electrode without causing cost raise. <P>SOLUTION: A method of manufacturing a chip resistor includes steps of preparing a base material substrate A in which a plurality of insulation substrates are aligned and integrated and a longitudinal break groove A1 and a lateral break groove A2 are engraved on its surface; forming a pair of right and left top surface electrodes 2 astride a portion of each of the insulation substrates and forming a resistance film 3; performing trimming adjustment so that a resistance value of the resistance film can be a predetermined value while measuring the resistance value while a probe B for conduction contacts both the top surface electrodes; forming side surface electrodes 6 on both the right and left end surfaces of each of the insulation substrates after breaking the substrate along the longitudinal break groove; and further breaking substrate along the lateral break groove A2. In this case, when the top surface electrodes 2 are formed, through hole 2a are formed on a portion overlapping over the longitudinal break groove A1 of the top surface electrodes 2. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
