<P>PROBLEM TO BE SOLVED: To provide a pressure-adhesive sheet capable of concealing personal information by using a piece of paper with a detachable adhesive, breaking no piece of paper when detaching the concealed piece of paper from the pressure-adhesive sheet, executing no adhesive restraint printing for preventing the piece of paper from breaking, and further causing no problem of manufacture when performing cutout processing at the corner of the pressure-adhesive sheet and to provide a method of manufacturing the pressure-adhesive sheet. <P>SOLUTION: The pressure-adhesive sheet is formed by connecting a substrate having a pressure-sensitive adhesion part at a fold part or a cut-off part, folding the substrate at the fold part to be overlapped or cutting off the substrate at the cut-off part to cause the cut substrates to be overlapped, and detachably adhering the substrates by the pressure-sensitive adhesive part. In a part of the substrate, a triangular corner-cut part consisting of vertices A, B, and C and setting the vertex B as a substrate corner part is formed and a remaining part after cut-off in the corner-cut part is deteriorated with respect to a pressure-sensitive adhesive composing the pressure-sensitive adhesive part near sides in obtuse angles of at least vertices A and C of the corner-cut part. <P>COPYRIGHT: (C)2013,JPO&INPIT |
