摘要:
An object of the invention is to provide a resistor element that makes it possible to adjust the resistance value of a precursor easily in producing a resistance element having a target resistance value from the precursor, as well as to the precursor and a related resistance value adjusting method. A precursor 70 has a meandering resistance pattern formed on a front surface 11 of a substrate 10 as well as at least three trimming lines. The precursor 70 is configured so as to be defined by a geometric sequence that satisfies Inequality 0.5αk
