PROBLEM TO BE SOLVED: To provide an energy ray-sensitive composition excellent in coatability, curability, and adhesion.SOLUTION: The energy ray-sensitive composition contains: a cationically polymerizable monomer mixture (1) containing as an essential component a bi- or higher functional symmetric cationically polymerizable monomer (1A); and an energy ray-sensitive acid generator (2). The energy ray-sensitive composition contains, based on 100 pts.mass of the cationically polymerizable monomer mixture (1), 5-50 pts.mass of the bi- or higher functional symmetric cationically polymerizable monomer (1A), and 50-95 pts.mass of an asymmetric epoxycycloalkyl type compound (1B) or 0.5-20 pts.mass of a monofunctional cationically polymerizable monomer (1C). 【課題】塗工性、硬化性及び接着性に優れるエネルギー線感受性組成物を提供すること。【解決手段】二官能以上の対称型カチオン重合性モノマー（１Ａ）を必須成分とするカチオン重合性モノマー混合物（１）及びエネルギー線感受性酸発生剤（２）を含有することを特徴とするエネルギー線感受性組成物であって、上記カチオン重合性モノマー混合物（１）１００質量部に対し、二官能以上の対称型カチオン重合性モノマー（１Ａ）５〜５０質量部、非対称型エポキシシクロアルキル型化合物（１Ｂ）５０〜９５質量部又は単官能のカチオン重合性モノマー（１Ｃ）０．５〜２０質量部を含有する。【選択図】なし
