る。The main component 1 is composed of a large number of cut pieces 2 of activated carbon fibers which are light in weight, have a large surface area and good adsorbability, and have the cut pieces 2 of activated carbon fibers. The surface of the cut short piece 3 of the small amount of the hot-melt fiber mixed therewith was partially bonded and connected as a binder to form a fine communication gap between the cut short pieces. Even in such a case, excellent filtration performance can be exhibited. In addition, since the innumerable cut pieces 2 of activated carbon fibers are intricately adhered and held on the surfaces of the cut pieces 3 of mixed hot-melt fibers, they do not fall off easily and can be used for a long time. In addition, the ratio of the communication gap occupied in the main body 1 integrally formed into a required shape can be determined arbitrarily depending on whether or not the pressure is applied during the molding or the degree of the pressure. It is also easy to make it suitable.

のである。As is clear from the description of the above embodiment, the present invention is based on a cut short piece of activated carbon fiber having a large surface area and good adsorbability as a main material, and a cut short piece of a small amount of hot-melt fiber mixed therewith. Because the cut short pieces of countless activated carbon fibers as the main material on the surface are intricately partially bonded and connected to form fine communication gaps between the cut short pieces, they are integrally molded into a main body of a required shape, It becomes a filter body that fully demonstrates the properties of activated carbon fiber, and is lightweight and has high filtration efficiency. Moreover, since the activated carbon fibers are cut short pieces, the cost of raw materials can be made relatively low because the broken parts and waste equivalents can be used without waste. In addition, the activated carbon fibers break during the manufacturing process or during handling, and the cut short pieces are used. Can also solve problems such as dropping and soiling the surroundings. Further, in such a filter, a cut short piece of activated carbon fiber as a main material and a small amount of cut short piece of hot-melt fiber are filled in a molding die having a required shape in a mixed state, and at least the surface of the hot-melt fiber is filled with this. By heating to a temperature at which it melts, it is possible to easily form a main body having a shape corresponding to an appropriate filter, and thus there is an advantage that it can be provided at low cost. Therefore, the present invention has a very high industrial value as a filter which has solved the problems of the conventional filter.
