Provided is a paper treatment agent with which improved touch feeling different from smoothness that has been conventionally studied is obtainable when a pressure is applied like nose blowing or the like.

A paper treatment agent of the present invention is a paper treatment agent containing (A) a polyhydric alcohol as a main component, the paper treatment agent contains (B) a sucrose fatty acid ester having an acyl group with more than 12 and less than 22 carbon atoms and an HLB of 11 or more and (C) an ionic surfactant, and it is characterized in that a mass ratio (C/B) of the component (C) to the component (B) is 0.65 to 24. According to the paper treatment agent of the present invention, when a pressure is applied to treated paper like nose blowing or the like, slick texture that is specific and distinctive smoothness which is non-conventional is obtainable.
