<P>PROBLEM TO BE SOLVED: To prevent the generation of curls at a peeling end part in peeling of a peeling base material, regarding a re-peelable overlapped sheet where a plurality of base materials are overlapped and then a predetermined base material is peeled. <P>SOLUTION: A marked part 13B for indicating a peeling start part is formed on a surface of an upper base material 41, an area corresponding to the marked part 13B, on a surface of a lower base material 15 is made to be a non-paste part 22C, a sticking material layer (adhesive layers 22A, 22B) where adhesive force due to an adhesive agent is divided into at least two levels from strong to weak is formed from the peeling start end of the non-paste part 22C in a peeling direction Toff toward the area of a peeling end in a diagonal direction, the peeling agent layer side of the upper base material is adhered thereon, and in the adhesive layers, the coating width b of the adhesive layer 22B of two sides continuous with the area of the peeling end except two sides is configured to be smaller in comparison with the coating width a of the adhesive layer 22A of the two sides at both sides from the peeling start end out of four sides except the non-paste part 22C. <P>COPYRIGHT: (C)2013,JPO&INPIT |
