Abstract:
A nitrogen oxide detecting sensor includes a gas detecting portion and electrodes electrically connected to the gas detecting portion. The gas detecting portion is composed mainly of an oxide compound having electric conductivity or semiconductivity. The oxide compound has a crystal structure of 2212 phase or resistivity ranging not more than 50 Ω cm. And, the oxide compound is expressed generally as:
Bi₂ Sr₂ (Ca 1-X Y X ) Cu₂ O₈ ± δ
(where, X is more than 0 but not more than 1 excluding 1, δ is more than 0 but less than 1 including 1).
Bi₂ Sr₂ (Ca 1-X Y X ) Cu₂ O₈ ± δ
(where, X is more than 0 but not more than 1 excluding 1, δ is more than 0 but less than 1 including 1).
