PROBLEM TO BE SOLVED: To provide a steam hot tool which provides a feeling of steam and a feeling of relaxation and improves a feeling of dry of the nose and the throat.SOLUTION: The steam hot tool is provided with a covering member which has a covering section for covering both the mouth and the nose of a user and a water vapor generator which is held on a user-facing surface of the covering section. A space is formed between the covering section and the face of the user upon use and the following formulae (1) to (3) are satisfied: (1) 300≤VG≤1500； (2) 40≤MV≤150； and (3) 5≤VG/MV≤25 (in formulae (1) to (3), VG represents a cumulative generation amount [mg] of water vapor emitted into the space within 10 minutes after the start of the generation of water vapor by the water vapor generator； and MV represents a volume [mL] of the space).SELECTED DRAWING: Figure 1【課題】蒸気感、リラックス感が得られ、鼻及び喉の乾燥感が改善される蒸気温熱具を提供する。【解決手段】蒸気温熱具は、使用者の口と鼻とを覆う被覆部を有する被覆部材と、前記被覆部の前記使用者側の面に保持される水蒸気発生体と、を備え、使用時に前記被覆部と前記使用者の顔とで挟まれた空間が形成され、下記式（１）～（３）を満たす。 ３００≦ＶＧ≦１５００ （１） ４０≦ＭＶ≦１５０ （２） ５≦ＶＧ／ＭＶ≦２５ （３）（式（１）～（３）中、ＶＧは前記水蒸気発生体の水蒸気発生開始から１０分間に前記空間内に放出される累積水蒸気発生量〔ｍｇ〕を示し、ＭＶは前記空間の容積〔ｍＬ〕を示す。）【選択図】図１
