Abstract
In an adhesive sheet, temperature dependence of a relative dielectric constant that is determined by a test for evaluating temperature dependence is equal to or less than 30%, and a 180° peel strength determined by a test for evaluating adhesiveness is equal to or greater than 0.20 N/mm. The adhesive sheet can inhibit the occurrence of malfunctioning of a capacitance-type touch panel in an environment of a wide temperature range from a low temperature to a high temperature, and can be included in a laminate for a touch panel and a capacitance-type touch panel.
