Abstract

PURPOSE:To improve the durability and responsive properties of solid electrolyte, by providing many cut windows having the aperture areas in a specific range to the inner side of outer circumferential protective cover of solid electrolyte of detector for the concentration of oxygen. CONSTITUTION:A surface of a outer circumferential protective cover 15 of a solid electrolyte 1 of the detector for the concentration of oxygen shown by figure is cut in the direction of the inner side to form many windows 15, and through holes 15c are provided. Cut pieces 15b are cut slantly so that the value of aperture area per one window 15a divided by that of the surface area of the part exposed to detecting gas of the electrolyte 1 is regulated to the range 0.003-0.009. Hereby, an electrode 3 is made not exfoliate by allowing the waste gas to collide with the electrolyte 1 at high speed and durability is improved and also, worsening of responsive properties is prevented.
