Abstract: A sheet (10) for a mask has a first fiber layer (11) and a second fiber layer (12). The second fiber layer (12) has a higher trapping ratio for particles having a particle diameter exceeding 1 μm and/or a smaller average fiber diameter than the first fiber layer (11). The basis weight of the second fiber layer (12) is from 1 to 20 g/m2. In a natural state, the second fiber layer (12) has a plurality of projections (13) projecting toward a surface of the second fiber layer (12) that is opposite to a surface of the second fiber layer (12) facing the first fiber layer (11) and depressions (14) that are each arranged between corresponding projections (13) of the plurality of projections (13). The depressions (14) have joined portions (15) where the second fiber layer (12) and the first fiber layer (11) are joined to each other.

Abstract: A skin-attaching sheet including an attaching portion configured for attaching to skin. The attaching portion includes a color-changeable layer that changes color following exposure to ultraviolet rays, and the attaching portion has a color difference (ΔE*ab) in an L*a*b* color system between before exposure and 10 seconds after exposure of 5 or more and 300 or less in a standard exposure test in which the attaching portion is exposed to ultraviolet rays in a moist state.
