摘要：
This invention is intended to provide a cigarette paper capable of reducing both a visible sidestream smoke amount and a carbon monoxide amount in a mainstream smoke. The invention provides a cigarette paper having a grammage of 40 to 55 g/m 2 and containing calcium carbonate in an amount of 18 g/m 2 or more. Where the primary particles of calcium carbonate having a columnar shape or a needle shape are used, the carbon monoxide amount in the mainstream smoke decreases significantly, as compared with the case where the primary particles of calcium carbonate having another shape are used.
