A paint film-protecting sheet, which is unwound from a roll for use, and in which occurrence of adhesive transfer at edges thereof is effectively prevented, and a method of manufacturing same are provided. The paint film-protecting sheet is in the form of a roll obtained by winding in a lengthwise direction a pressure-sensitive adhesive sheet formed of a substrate in continuous sheet form and a pressure-sensitive adhesive layer disposed on the substrate. The substrate comprises a resin component made primarily of polyethylene resin or polypropylene resin. The paint film-protecting sheet, after being unwound from the roll, has a percent shrinkage, in the lengthwise direction, of not greater than 1.2% when heated at 80° C. for 1 hour.
