PROBLEM TO BE SOLVED: To provide a protecting sheet which is superior in curved surface followability, does not easily fracture a substrate, is eco-friendly and is in particular suitable for protecting an automobile in transit. SOLUTION: This relates to a protecting sheet whose mean value of a warping hardness to both front side and back side in the fiber flow direction is in the range of 0.03-0.4 gf cm<SP>2</SP>/cm and whose mean value of warping hardness to both front side and back side in the direction directly crossing the fiber flow direction is in the range of 0.01-0.3 gf cm<SP>2</SP>/cm. The sheet comprises a substrate mainly using a natural fiber where an impregnant mainly using a natural component is impregnated and a natural adhesive. COPYRIGHT: (C)2004,JPO&NCIPI
