PURPOSE:To provide a paste for an O2 sensor which operates even at a low temperature around 250 deg.C and, even at a high temperature of 600 deg.C or higher, its electromotive force varies in a predetermined response time upon the variation of an oxygen concentration, thereby stably operating in a range from a low temperature to a high temperature. CONSTITUTION:The surface of fine particles of Pt and/or Pd being coated with Ag by an electroless deposition, the Ag coated fine particles are kneaded with an organic binder and an organic solvent so as to produce a paste for an O2 sensor. |
