<P>PROBLEM TO BE SOLVED: To provide a double-sided adhesive sheet intended for sticking a sander with a sandcloth and enabling both of the unevennesses and undulations of a to-be-sanded object to be eliminated in a short time through a series of steps or simultaneously. <P>SOLUTION: The double-sided adhesive sheet is such one that adhesive layers are provided respectively on both sides of a foam sheet meeting the following requirements: when the difference between the maximum thickness and the minimum thickness within 1 m<SP>2</SP>(=thickness range:μm) and 25%compression hardness(MPa) are represented as x-axis and y-axis respectively, the thickness range and the 25%compression hardness fall within the range encircled by the 6 coordinates (0, 0.1), (200, 0.1), (200, 0.2), (100, 0.3), (100, 1.0) and (0, 1.0). <P>COPYRIGHT: (C)2004,JPO |
