Zusammenfassung:	Provided is a photoreactive composition which, even when used for producing a molded object that poorly transmits light, can be efficiently hardened to the deep portion thereof. The photoreactive composition comprises a vinyl monomer and a filler. When the photoreactive composition, which comprises a vinyl monomer and a filler, is poured into a test tube with a diameter of 0.6 cm and a height of 5 cm to a height of 3 cm from the bottom of the test tube, irradiated with light from above the test tube using an LED lamp having a center wavelength of 365 nm at a light intensity of 30 mW/cm2 for 360 seconds, and allowed to stand at 25 DEG C for 24 hours, then the conversion into polymer of the vinyl monomer present in a position 1 cm above the bottom of the test tube is 90% or higher.
