Kind Code:
A1
Abstract:
The present invention relates to: a sheet of double-sided pressure-sensitive adhesive pieces which comprises a release film and, superposed thereon, double-sided pressure-sensitive adhesive pieces having an even thickness and which includes unnecessary double-sided pressure-sensitive adhesive portions that are separated from respective double-sided pressure-sensitive adhesive pieces so as to be adjacent thereto and have the same thickness as the double-sided pressure-sensitive adhesive pieces; and a method for bonding a component to another component or to a substrate with the sheet. The sheet of double-sided pressure-sensitive adhesive pieces according to the present invention is obtained by die-cutting a double-sided pressure-sensitive adhesive sheet, and the double-sided pressure-sensitive adhesive pieces suffer little partial peeling or deformation. According to the method of the present invention, components can be bonded with satisfactory precision using such sheet.
