Provided is a separator for a nonaqueous electrolyte battery, including a porous substrate and an adhesive porous layer that is provided on one side or both sides of the porous substrate and contains an adhesive resin. On the surface on the side where the porous substrate has the adhesive porous layer, the separator has a dynamic coefficient of friction of 0.1 or more and 0.6 or less and a ten-point average roughness (Rz) of 1.0 μm or more and 8.0 μm or less. |
