Abstract
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 precursorhas a meandering resistance pattern formed on a front surfaceof a substrateas well as at least three trimming lines. The precursoris configured so as to be defined by a geometric sequence that satisfies Inequality 0.5α<α<α, where αis the general term of the sequence that is obtained by arranging, in descending order, resistance value increases of the precursor at the time of cutting of the respective trimming lines and normalizing the thus-arranged resistance value increases by an initial resistance value of the precursor in a state that none of the trimming lines are cut.
