Beschreibung
Zusammenfassung:	[Problem] To provide: an active energy ray-curable composition which has little residue of unreacted products or low-molecular-weight decomposed products, does not cause odor or bleeding, and has excellent heat resistance and heat resistance; and a molded article for various applications, which uses the active energy ray-curable composition. A cured product having high safety, durability and transparency can be obtained, can be completely cured even with long-wavelength light rays having a wavelength of 350 nm or more, and has high transparency. [Solution] This active energy ray-curable composition contains a polymerizable photoinitiator (A) having one or more benzophenone groups and one or more ethylenically unsaturated groups per molecule, and a polymerizable compound (B) (excluding the polymerizable photoinitiator (A)) having one or more ethylenically unsaturated groups per molecule, and the content of components having a molecular weight of less than 1000 in the cured product is less than 10%.
