Abstract

The invention discloses a filter-tipped cigarette comprising a filter tip. The filter tip comprises a plurality of filter elements twisted together by mutually winding. All the filter elements are cellulose acetate fiber bundles. In the invention, since the filter elements are disposed in the way of winding, a total length of the filter elements is increased, a travel of a smoke passing through the filter elements is thereby increased, and thus harmful ingredients in the cigarette are filtered more thoroughly.
