Cigarette wrapper and cigarette

Abstract

A cigarette has a tobacco section in which cut tobacco is wrapped with a cigarette wrapper, a filter section connected to one end of the tobacco section, and a tip paper integrally connecting the tobacco section to the filter section in a manner to cover the proximal end portion of the tobacco section and the filter section and provided with ventilation holes formed in a circumferential direction in positions apart from the smoking end of the filter section. The tobacco section has a rod length of 30 to 46 mm, and a cut tobacco filling density of 180 to 270 mg/cm 3 . The cigarette wrapper has a basis weight of 17 to 21 g/m 2 , a mixing ratio of a calcium carbonate filler of 16 to 25% by weight, and a calcium carbonate content of 3 g/m 2 or more. The cigarette provides at least six puffs under a standard smoking condition.
