Title:
Double-sided adhesive sheet
Document Type and Number:
Japanese Patent JP6310062
Kind Code:
B2
Abstract:
A double-sided pressure-sensitive adhesive sheet (1) used to adhere a first hard object (4) and a second hard object (5) together. Said double-sided pressure-sensitive adhesive sheet (1) has a first pressure-sensitive adhesive surface (11S) that adheres to the first hard object (4) and a second pressure-sensitive adhesive surface (12S) that adheres to the second hard object (5). The ratio (F1/F2) of the strength (F1) of the adhesion between the first pressure-sensitive adhesive surface (11S) and the first hard object (4) to the strength (F2) of the adhesion between the second pressure-sensitive adhesive surface (12S) and the second hard object (5) is between 0.0001 and 0.1, inclusive. This double-sided pressure-sensitive adhesive sheet (1) excels in terms of reworkability, and the first hard object (4) and the second hard object (5) bonded together using this double-sided pressure-sensitive adhesive sheet (1) can be separated such that at least the first hard object (4) can be reused.
