HEAT RAY TYPE SEMICONDUCTOR GAS DETECTION ELEMENT AND GAS DETECTOR

摘要

PROBLEM TO BE SOLVED: To provide a technique efficiently achieving the suppression of power consumption when the heat ray type semiconductor gas detection element is formed so that the vol. thereof becomes small. SOLUTION: A responsive part 3 formed from a semiconductor based on tin oxide so as to cover a noble metal wire coil 2 is provided to this element and formed so that the long diameter d2 thereof becomes 1.5 times or less the short diameter d3 thereof and the vol. thereof becomes 8.2×10<-3> mm<3> or less. Further, the distance from the coil part 2a of the noble metal wire coil 2 to the outer surface of the responsive part 3 is set to 50μm or less.
