摘要：
To provide a non-moisturizing high-grade type tissue paper having excellent softness.
The problem is solved by a two-ply tissue paper to which a polyol is not applied by external addition. The tissue paper has a basis weight per ply of 14.0 to 17.0 g/m 2 , a paper thickness for two plies of 160 to 220 µm, and a water content of 4.0 to 9.0% by mass, contains 0.15 to 0.45% by mass of an oily component to be extracted with diethyl ether, and has a bending rigidity of less than 0.006 gf·cm/cm in CD (cross direction) and a bending recovery force of less than 0.005 gf·cm/cm in CD.
