To provide a method for producing a non-slip sheet by which the non-slip sheet having a non-slip layer composed of a low-density ethylene-α-olefin copolymer having high non-slip performances that can withstand even uses for prevention of load shifting can be obtained, and to provide the non-slip sheet.

There is provided the method for producing the non-slip sheet by which the non-slip sheet is obtained by piling up the non-slip layer composed of the ethylene-α-olefin copolymer to one surface or both surfaces of a base material according to extrusion laminating with a cooling roll or thermocompression bonding with a heating roll. In the method for producing the non-slip sheet, the density of the ethylene-α-olefin copolymer is 0.800-0.895 g/cm3, and the value of Rz on the surface of the cooling roll or the heating roll contacting the non-slip layer is 0.5-2.0 μm. The non-slip sheet is obtained by the method for producing the non-slip sheet, and the non-slip sheet has a slip tilt angle of ≥50° according to the tilt method of JIS P8147 [2010 standard].
