PROBLEM TO BE SOLVED: To provide an aroma tool which results in the low degree of a change in the degree of aroma with use and offers favorable usability.SOLUTION: This tool includes: a housing section (1a) of which one side is an opening (1a2), and in which a liquid can be housed; a gas-permeable sheet (2) that is mounted to the housing section (1a) to block the opening (1a2); a gas-nonpermeable sheet (3) which covers a region corresponding to the opening (1a2) in the gas-permeable sheet (2) and which is mounted to the gas-permeable sheet (2) so as to be able to be peeled from the gas-permeable sheet; and a liquid aromatic agent (5) which is housed in a space (V1) surrounded by the housing section (1a) and the gas-permeable sheet (2). The amount of the housed liquid aromatic agent is an amount that satisfies RG≤0.5 on the assumption that the area of the region corresponding to the opening (1a2) in the gas-permeable sheet (2) is AR, the area of a region coming in contact with the liquid aromatic agent (5) is AR1, and RG=AR1/AR is a liquid aromatic agent contact ratio RG.SELECTED DRAWING: Figure 1【課題】使用経過に伴う芳香強さの変化度合いが小さく良好な使用感が得られる芳香具を提供する。【解決手段】一方側が開口部(1a2)とされ液体を収容可能な収容部(1a)と、開口部(1a2)を塞いで収容部(1a)に取り付けられた気体透過性シート(2)と、気体透過性シート(2)における開口部(1a2)に対応した範囲を覆い、気体透過性シート(2)に対し剥離可能に取り付けられた気体不透過性シート(3)と、収容部(1a)と気体透過性シート(2)とに囲まれた空間(V1)内に収容された液体芳香剤(5)と、を備える。気体透過性シート(2)における開口部(1a2)に対応した範囲の面積をARとし液体芳香剤(5)と接触した範囲の面積をAR1としRG=AR1/ARを液体芳香剤接触比RGとしたときに、収容された前記液体芳香剤の量は、RG≦0.5 となる量である。【選択図】図1
