Abstract
An adhesive sheet includes an adhesive composition layer. The adhesive composition layer is formed using a composition including a polythiol compound, a compound having plural epoxy groups, a radical generator and an amine-based catalyst. The ratio (Ep/SH (epoxy groups/thiol groups ratio)) of a total molar number (Ep) of epoxy groups contained in the compound having plural epoxy groups to a total molar number (SH) of thiol groups contained in the polythiol compound is higher than 0.20 but lower than 1.00.
