An acid generator which does not contain a toxic metal, has sufficient cationic polymerization performance and crosslinking reaction performance, and a cured product using the same can provide sufficient reliability particularly in electrical characteristics (insulation reliability). Etc. The present invention relates to an acid generator comprising an onium borate salt represented by the following general formula (1), heat or active energy comprising the acid generator and a cationically polymerizable compound. Chemical amplification comprising a linear curable composition and a component (A) comprising the acid generator, a component (B) which is an alkali-soluble resin having a phenolic hydroxyl group, and a crosslinking agent component (C) Type negative photoresist composition.
