Cigarette filters of various structures have been developed for the purpose of removing harmful components from cigarette towels. The most widely used of these is cigarette filters made of cellulose acetate fibers. In recent years, due to health concerns for smokers, cigarette filters with a large fiber content or made from cellulose acetate fibers with a small filament fineness have been used to reduce the width of the cigarette that enters the smoker's mouth. We have succeeded in reducing the amount of harmful ingredients. However, with such cigarette filters, the resistance to slight opening during smoking increases significantly, placing a heavy burden on the smoker and reducing the aroma and taste, which is a major problem in that the smoking sensation is inhibited.

Therefore, the inventors of the present invention have developed a cigarette filter that can reduce the amount of harmful components in the tobacco waving that enters the smoker's mouth without placing a large burden on the smoker, and can provide the smoker with a high flavor and taste. With the aim of developing a The present invention has been completed based on the discovery that the object can be achieved by wrapping the filter around the outer periphery of the filter so that the formed convex portion has a structure that substantially blocks the airflow flowing through the former groove.
