BLADE DIE, ADHESIVE SHEET MANUFACTURING APPARATUS, PEELING METHOD AND MANUFACTURING METHOD OF ADHESIVE SHEET

PROBLEM TO BE SOLVED: To provide a blade die, adhesive manufacturing apparatus, a peeling method and a manufacturing method of the adhesive sheet capable of preventing generation of residual adhesion phenomenon when an unnecessary part of one of two sheets laminated through an adhesive agent layer is peeled off with the adhesive agent layer.SOLUTION: A blade die 21 forms a first notch with closed area shape at least to a frist sheet and an adhesive agent layer of a laminate R1 having the adhesive agent layer on one side face of the first sheet and obtained by laminating a second sheet through the adhesive agent layer and peels an outside region from the first notch of the first sheet together with the first sheet and the adhesive agent layer to make an inner region from the first notch the adhesive sheet, and has a base plate 210, a first incised blade 211 with the closed area shape supported by the base plate 210 and forming the first notch from the first sheet side of the laminate R1, and a second incised blade 212 supported by the base plate 210 at the outer region of the incised blade 211 and of which a plurality are arranged along a direction intersected with a peeling direction along which the outer region of the first sheet is peeled.
