A cigarette filter according to an embodiment of the present invention comprises: a filter unit having a column portion filter member forming a column portion, a mouth portion filter member forming a mouth portion, and a filter cavity including a flavor capsule positioned between the column portion filter member and the mouth portion filter member and containing a flavor material; a dispersion preventing plug wrap wrapping at least one portion of the filter unit and preventing the flavor material contained in the flavor capsule from being dispersed, wherein surface energy of the dispersion preventing plug wrap may be relatively lower than surface energy of the flavor material contained in the flavor capsule. The embodiment of the present invention may prevent the flavor material from being dispersed to the outside of the plug wrap and in the direction of the column portion, accordingly prevent the flavor material from being stained on a hand during smoking and maintain combustibility of the column portion, thereby enhancing smoking satisfaction. 본 발명의 실시예에 따른 담배 필터는, 각초부를 형성하는 각초부 필터부재와, 구부를 형성하는 구부 필터부재와, 각초부 필터부재 및 구부 필터부재의 사이에 개재되며 향 물질이 함유된 향 캡슐을 포함하는 필터 캐비티를 포함하는 필터부; 및 필터부의 적어도 일부분을 감싸며, 향 캡슐에 포함된 향 물질의 번짐을 방지하는 번짐방지 필터권지;를 포함하며, 번짐방지 필터권지의 표면에너지는 향 캡슐에 포함된 향 물질의 표면에너지에 비해 상대적으로 낮을 수 있다. 본 발명의 실시예에 따르면, 향 물질이 필터권지의 외측 및 각초부 방향으로 번지는 것을 방지할 수 있으며, 이를 통해 흡연 시 향 물질이 손에 묻는 것을 방지할 수 있고 아울러 각초부의 연소성을 유지시킬 수 있어 흡연 만족도를 향상시킬 수 있다.
