PROBLEM TO BE SOLVED : To provide a surface protective sheet in which the surface of a resin in a supporting substrate is provided with a pressure-sensitive adhesive layer, and which is endowed with both a higher re-peelability and higher non-staining properties.
SOLUTION : The surface protective sheet 1 has a supporting substrate 10 and a pressure-sensitive adhesive layer 20 provided on a front side 10a of the supporting substrate 10. At least a portion of the supporting substrate 10, including the front side 10a, is made of a resin material that is composed primarily of a polyolefin and includes (A) : at least one of a fatty amide and a fatty acid metal salt, and (B) : an antioxidant. The content CA of the component (A), based on the mass of the resin material, is from 50 ppm to 500 ppm.
