Paper plug and flavor inhalation article

Abstract

Provided is a paper plug having a filler and an inner plug wrap that wraps the filler, wherein the average of the areas of pores formed in a cross section perpendicular to the long axis is less than 0.15 mm2, and the firmness in a direction perpendicular to the long axis, which is defined by formula (1), is greater than 75%, and formula (2) is satisfied.　(1) Firmness (%) in the direction perpendicular to the long axis = (Dd / Ds) × 100 (2) (The pressure drop per 1 mm in length in the long axis direction) / (the packing density of the filler) < 22 mmH2O×mm2 / mg
