PROBLEM TO BE SOLVED: To rapidly decompose ozone generated as a byproduct from an anode so that it is prevented from being dispersed by arranging an air filter wherein an ozone-decomposing catalyst is borne by a filter material on the anodic side of an electrochemical element, and forming a shielded space covering the anode with the air filter. SOLUTION: An air filter 7 positioned parallel with the electrode face of an anode 2 specifically spaced from the air filter 7 is arranged on the anode 2 side faced toward the interior of an airtight container 9. This air filter 7 comprises an unwoven cloth filter 7 bearing a fibrous or a granular active carbon as an ozone decomposing catalyst mixed with a filter fiber. The peripheral edge part of the air filter 7 is tightly fastened to the surface of a resin frame 11 fitted into the peripheral edge part of an electrochemical element 1 to form a shielded space 8 covering the anode 2. Thus it is possible to prevent the ozone generated as a byproduct by the anode 2 from being flowed into the storage space 13 of the airtight container 9.
