Abstract: Provided is an α-aminoalkylphenone compound that has good stability and low sublimability, efficiently generates radicals when irradiated with a bright line at 365 nm (I line) or the like, and is useful as a polymerization initiator to be used in a radically polymerizable composition. The α-aminoalkylphenone compound is represented by Formula (I) mentioned below. In Formula (I) mentioned above, it is preferable that R11 is a nitro group, an alkoxy group having 1 to 12 carbon atoms, or an alkoxycarbonyl group having 1 to 12 carbon atoms. The α-aminoalkylphenone compound can be preferably used in a polymerization initiator.
