摘要：
A skin substitute membrane includes a surface on one side including a groove-shaped depressed portion and a planar portion, the depressed portion having a cross section having a chamfered V-letter shape, the surface having an arithmetic mean roughness Sa of more than or equal to 10 μm to less than or equal to 50 μm. The depressed portion has a width of more than or equal to 50 μm to less than or equal to 500 μm and a depth of more than or equal to 30 μm to less than or equal to 150 μm. A spectral transmittance for light of more than or equal to 290 nm to less than or equal to 400 nm in wavelength is more than or equal to 50% and less than or equal to 100%.
