Abstract: A resistor trimming method which brings about a good surge resistance and which allows a quick and reliable trimming, including the steps of forming a first slit 141 from an edge A of a resistor 11 formed between a pair of electrodes 12a and 12b provided on an insulating substrate 13, the first slit being in the proximity of and in parallel to one electrode 12a, forming a second slit 142 as a continuation of the first slit 141 toward the other one of the electrodes 12b, the second slit 142 being perpendicular to the first slit 141, and forming at least one approximately L-shaped slit 143 as a continuation of either one of the first slit 141 or the second slit 142.

Abstract: A resistor trimming method includes the steps of: forming a first slit from an edge of a resistor interconnecting first and second electrodes provided on an insulating substrate in the proximity of and parallel to the first electrode; forming a second slit as a continuation of the first slit toward to the second electrode perpendicularly to the first slit; forming a third slit from a point of the edge of the resistor and parallel to the first electrode, the point being shifted from the first slit toward the second electrode, the third slit having a greater length than the first slit in a direction along the first electrode; and forming a fourth slit as a continuation of the third slit toward to the second electrodes perpendicularly to the first slit.
