点があった。2. Description of the Related Art A conventional air purifier uses a honeycomb substrate made of a thin aluminum sheet or kraft paper as shown in Japanese Patent Publication No. 3-80043 and Japanese Patent Publication No. 4-26885. It was formed by sandwiching while bonding. Further, as shown in Japanese Patent Publication No. 7-38927, an electrostatic filter for dust collection is welded to the deodorizing filter thus formed, so that a filter for an air purifier in which dust collection and deodorization are integrated. Had formed. However, such a conventional technique has a drawback that the deodorizing filter and the dust collecting filter are flat and cannot have a large surface area, and the deodorizing efficiency and the dust collecting efficiency are not sufficiently improved.

た。On the other hand, as shown in Japanese Patent No. 2508682, a filter for air purification folded in a pleated shape is provided with a first filter made of an odor adsorbent and a filter for dust collection. By forming the second filter medium for filtering fine particles and the catalyst body sandwiched and supported between the first and second filter materials, a large surface area can be obtained. However, this method requires two or three sheets.
There is a drawback that the pressure loss when air is flowed is high because the sheets are stacked, and the deodorizing efficiency and dust collecting efficiency are not sufficiently increased. Furthermore, there is a drawback that, since the emphasis is placed on increasing the surface area, a large amount of the deodorizing material cannot be obtained, and it is not possible to cope with all kinds of odor components.

た。As disclosed in Japanese Utility Model Registration No. 2541895, two filters are used as a deodorizing filter, one being a sheet containing activated carbon and the other being a sheet containing a substance which reacts with an acidic and / or alkaline gas. By forming the sheet into a structure in which the sheets are processed into a pleated shape, a large surface area can be obtained. However, in this method, as a sheet containing a substance that reacts with an acidic and / or alkaline gas, a sheet obtained by impregnating malic acid and ferrous sulfate on a nonwoven fabric of synthetic fibers is used as an example. Since the surface area is substantially determined by the surface area of the nonwoven fabric, and the surface area reacting with the malodorous substance is small, there is a disadvantage that the deodorizing efficiency is not sufficiently increased.
