To provide an element for a deodorization catalyst which his compact and manufactured at a low cost and by which the temperature of a deodorization catalyst can be efficiently heightened by rolling a composite sheet produced by overlaying a corrugated sheet of a metal and a flat sheet of a metal round the outer circumference of a heating axial body in a manner the corrugated sheet is set in the inner side.

In the case an element for a dedorization catalyst is assembled, a composite sheet 14 is constituted by overlaying a corrugated sheet 12 produced by corrugating, for example, a stainless sheet and a flat sheet 13 made of a similar material. The end parts of the corrugated sheet 12 and the flat sheet 3 of the composite sheet 14 are spot-welded in the outer circumferential face of a heating axial body 11 and then the composite sheet 14 is rolled in multilayers in a manner the corrugated sheet 12 is set in the inside. Then, of the element for a dedorization catalyst produced by spot-welding the end part of the flat sheet 13 positioned in the outermost side of the rolled sheet in the surface of the flat sheet 13 itself, the space formed by the corrugated sheet 12 is used as a gas passing route and a known deodorization catalyst is deposited on the walls of the gas passing route to obtain a deodorization apparatus.
