Pressure-sensitive adhesive sheet for retaining elements and method of producing elements

摘要

A pressure-sensitive adhesive sheet for retaining elements according to an embodiment of the present invention includes a base material layer and a pressure-sensitive adhesive layer provided on the base material layer and capable of being cured by an external stimulus. A crack-generating elongation represented by the following equation in a case where the pressure-sensitive adhesive sheet is elongated in a state where the pressure-sensitive adhesive layer is cured is larger than 115%.
