MANUFACTURING METHOD OF RESISTANCE ELEMENT, AND STRESS SENSOR USING SAME FOR OPERATING ELECTRONIC APPLIANCE

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a resistance element wherein the generation of its crack can be prevented.

SOLUTION: The manufacturing method is performed through a resistance-value adjusting process wherein a desired resistance value is obtained by heating a resistor 1 while scanning the surface of the resistor 1 without forming any groove in the resistor 1. An example of the foregoing heating means is a laser projection. Also, the manufacturing method is performed through the resistance-value adjusting process wherein the desired resistance value is obtained by so adjusting a laser irradiating and heating region 4 as to include in it the whole of the region of the resistor 1 or the most thereof, and by adjusting a laser irradiating time/a laser power value.
