Title
(JA) ガスセンサ、ガス検出装置、ガス検出方法及びガスセンサを備えた装置
Abstract
(JA)

ガス検出性能を向上することができるとともに、個々のガスセンサの出力特性のばらつきを抑制できるガスセンサ、ガス検出装置、ガス検出方法及びガスセンサ、ガス検出装置を備えた装置を提供する。
ガス検出装置(10)は、感熱抵抗素子(2)と、前記感熱抵抗素子(2)に介在物がなく溶接された状態で接続されたリード部(22b)と、前記感熱抵抗素子(2)と熱的に結合されるとともに、加熱により特定のガス分子が脱離される多孔性のガス分子吸着材料(3)とを有するガスセンサ(1)と、前記感熱抵抗素子(2)に電力を供給して、感熱抵抗素子(2)を加熱する電力供給部とを備えている。
