Abstract

This invention provides a photocurable composition, a cured product obtained by curing the above composition and a method for manufacturing the same, a laminate containing the cured product and a method for manufacturing the same, a semiconductor device and a method for manufacturing the same, and a novel compound. The photocurable composition contains a photoradical polymerization initiator and a curable compound. The photoradical polymerization initiator has 2 to 4 (ketoxime) groups in one molecule that are single-bonded to an aromatic ring, and at least one of the (ketoxime) groups is in an adjacent position to a substituent X, which is a substituent for oxygen, sulfur, or nitrogen atoms that are bonded to the aromatic ring.
