The sulfonium salt does not contain a toxic metal and exhibits higher cationic polymerization performance and crosslinking performance than a tetrakis(pentafluorophenyl)borate salt. The heat- or photo-acid generator contains the sulfonium salt. The sulfonium salt is formed of a sulfonium cation selected from a group represented by general formulas (1), (9), (10) and (11) described below and a gallate anion represented by formula (a). The heat- or photo-acid generator contains the sulfonium salt. The heat- or energy ray-curable composition contains the acid generator and a cationically polymerizable compound. A cured product can be obtained by curing the same.
