Abstract

A cigarette paper exhibiting a low flame-spreading property, includes, on one surface of a base cigarette paper containing a filler in an amount of 2 to 6 g/m 2 and having a basis weight of 16 to 22 g/m 2 , burn-suppressing regions coated with a burn-suppressing agent, provided spaced apart from each other, in which the total coating amount of the burn-suppressing agent corresponds to 0.2 to 1.8 g per m 2 of the coated portion.

1 . A cigarette paper exhibiting a low flame-spreading property, comprising, on one surface of a base cigarette paper containing a filler in an amount of 2 to 6 g/m 2  and having a basis weight of 16 to 22 g/m 2 , burn-suppressing regions coated with a burn-suppressing agent, provided spaced apart from each other, wherein a total coating amount of the burn-suppressing agent corresponds to 0.2 to 1.8 g per m 2  of the coated portion.
