Abstract
A long-fiber nonwoven fabric includes: a fiber including a thermoplastic resin as a main component, in which the long-fiber nonwoven fabric has a surface roughness Rz of 25.0 μm or more and 50.0 μm or less on both surfaces, and an absolute value of a difference between the surface roughness Rz of one surface and the surface roughness Rz of the other surface is 4.0 μm or more and 10.0 μm or less.
