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 (1); 40≤;MV≤;150 (2); and 5≤;VG/MV≤;25 (3), where 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.
