Abstract: Disclosed is a filter for tobacco smoking which comprises a filter tip having a space therein, with flavor-sealed particles being contained in the space. The flavor-sealing particles are composed of a natural polysaccharide, or its derivative, and diluent agent, and are destroyed, in order to release the flavor sealed therein, by the application of a force to the outer surface of the filter which is greater than a force normally applied to the filter in a smoking action. According to the present invention, the flavor sealed in the particles can be released without the particles being burnt at the time of smoking.
