PROBLEM TO BE SOLVED: To provide an excellent protective sheet for a coated surface, which has assured air permeability and light transmittance, can suppress the disturbance of a coated surface, and can allow smooth spontaneous curing after spontaneous drying. SOLUTION: This sheet is made of a porous polymer sheet of which the surface to be adhered to the object to be protected has an average surface roughness of 1-10μm, which has a plurality of open cells which pierce through the sheet in the direction of its thickness and has a Gurley number X in the following range: (0<=X<=5)sec/100cm<3> . |
