Abstract: Provided is an oxygen sensor element that enables conservation of electric power without diminishing sensor properties. In order to achieve this, a structure is obtained by covering, with a heat insulation layer, an outer surface of a ceramic sintered compact serving as a sensing layer comprising the composition LnBa2Cu3O7-δ (wherein Ln is a rare-earth element), a heat insulation material, namely, the composition Ln2BaCuO5, is used as the heat insulation layer, and 20 mol% of LnBa2Cu3O7-δ is added to said composition. As a result, interlayer peeling and cracking can be prevented from occurring due to the sinter behavior of the heat insulation layer approaching the sinter behavior of the sensing layer, and by adopting a sandwiched structure in which the sensing layer is interposed between heat insulation layers, the conservation of electric power is made possible by reducing the amount of heat dissipated from the sensing layer.
