摘要： 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.
