Abstract
An oxygen concentration cell having a high peeling resistance of the electrode and an excellent response property can be obtained by a method wherein electrode-adhering particles, which consist essentially of a specifically limited amount of stabilized or partially stabilized zirconia granulated particles having a spherical shape and a particle size of not smaller than 44 .mu.m and a specifically limited amount of stabilized or partially stabilized zirconia fine particles having a particle size of not larger than 10 .mu.m as a sintering aid, are applied and adhered to the surface of a matrix consisting of stabilized or partially stabilized zirconia, the resulting assembly is sintered to form monolithically a large number of convex portions on the matrix surface, an electrode is adhered to the matrix surface having the convex portions monolithically formed thereon, and further a heat-resistant ceramic protecting film is adhered to the electrode film.
