<P>PROBLEM TO BE SOLVED: To provide a method for evaluating the cutting amount into a peeling base material of a laminated type adhesive sheet, in consideration of the necessity of evaluation and control of an entering amount (cutting amount) of a precut blade into the peeling base material in some way when manufacturing the adhesive sheet in order to sufficiently suppress failures of peeling an adhesive layer, a viscous layer and a base material film from the precut peeling base material. <P>SOLUTION: The method for evaluating the cutting amount of the adhesive sheet having a cut part evaluates the cutting amount on the basis of a breaking force (breaking load) when the cut part of the adhesive sheet is pressed to a push-pull gauge jig and a film of the adhesive sheet is broken. <P>COPYRIGHT: (C)2012,JPO&INPIT |
