PROBLEM TO BE SOLVED: To improve the reliability on durability related to degradation of an electrode in a high-molecular solid-electrolyte-type gas sensor. SOLUTION: A pair of platinum electrodes 2, a high molecular solid electrolyte film 3, and a seal coated film 5 are laminated on one of the surfaces of a porous body 1 having penetrating ventilation holes, and a porous catalyst body 4 is formed in a partial region of the other surface. Therefore, the porous body 1 having penetrating ventilation holes restrains or blocks the inflow of gas for degrading an electrode into the platinum electrodes 2 to prevent degradation of the platinum electrodes 2. |
