A steam heating tool includes a cover member that has a cover portion covering a mouth and a nose of a user, and a steam generator that is held on a surface of the cover portion on a side of the user, in which a space interposed between the cover portion and a face of the user is formed at a time of use, and the steam heating tool satisfies following formulae (1) to (3). 300 ‰¤ VG ‰¤ 1,500 40 ‰¤ MV ‰¤ 150 5 ‰¤ VG / MV ‰¤ 25 In the formulae (1) to (3), VG represents a cumulative steam generation amount [mg] released into the space for 10 minutes from a start of steam generation of the steam generator, and MV represents a volume [mL] of the space.
