Title:
STRAIN GAUGE AND PRODUCTION METHOD FOR STRAIN GAUGE
Document Type and Number:
WIPO Patent Application WO/2019/093373
Kind Code:
A1
Abstract:
Provided is a production method whereby a strain gauge having a resistor having a desired resistance value can be produced with a good yield. This production method for strain gauges includes: the formation of a laminate 20 by alternately forming a metal layer 22 and an etching stop layer 24 upon a base material; and patterning the laminate 20 and forming the resistor. The uppermost metal layer 22b (22d) may be removed by etching, in accordance with the resistance value of the resistor.
