<p>PROBLEM TO BE SOLVED: To provide a bubble sheet body capable of exerting a widespread magnetic effect.SOLUTION: A bubble sheet body is characterized in that it is obtained by laminating a flat base sheet Bs to a cap sheet Cs having a plurality of projecting caps C formed by using vacuum forming roll that is recessedly provided with a number of suction cavities for forming the cap C, and the caps C are provided with a magnet M that is unfixed and can freely move, and are distributed across the sheet. Also, the magnet M can freely change the orientation of the magnet polarity.</p> |
