SULFURIZATION DETECTION RESISTOR

WIPO Patent Application WO/2020/162067

A1

Provided is a sulfurization detection resistor capable of accurately and simply detecting a degree of sulfurization. A sulfurization detection resistor 10 includes a rectangular parallelepiped insulating substrate 1; a first surface electrode 2 and a second surface electrode 3 formed on both end portions of a main surface of the insulating substrate 1; a plurality of sulfurization detection conductors 4 connected in parallel to the first surface electrode 2; a plurality of resistors 5 connected between each sulfurization detection conductor 4 and the second surface electrode 3; and a protective film 6 formed so as to cover a portion of the sulfurization detection conductors 4 and the entirety of the resistors 5. Each of the sulfurization detection conductors 4 includes a sulfurization detection section 4a that is not covered by the protective film 6 and that faces another sulfurization detection section across a predetermined gap G. Each of the sulfurization detection conductors 4 is formed from a material having a different copper content, and the gaps G formed between the sulfurization detection conductors 4 are configured to conduct at timings that differ in response to increases in the cumulative sulfurization amount.
