An eye-use steam-generating heating sheet contains a steam-generating composition, which is covered with at least a first moisture-permeable sheet and a second moisture-permeable sheet in that order. The first moisture-permeable sheet has a moisture permeability of at least 600 g/m2/24 hrs, the second moisture-permeable sheet has a moisture permeability has a moisture permeability of 700 to 3000 g/m2/24 hrs, the first moisture-permeable sheet and the second moisture-permeable sheet are provided such that a steam accumulation space is formed therebetween, and at least one of the moisture-permeable sheets covering the steam-generating composition has a water resistance of at least 400 mm. This eye-use steam-generating heating sheet is sealed for storage.
