To provide initiators in two components having no discoloring after polymerization and excellent polymerization-curability under the existence of water, and provide a polymerizable composition using the initiators in two components. The initiators in two components are for polymerizing and curing a (meth)acrylate compound, and the initiator includes (a) a peroxide being compatible or soluble with water, (b) an aromatic sulfinic acid compound, (c) a tert-amine compound, and (d) water. The polymerizable composition uses the initiators in two components. Particularly, preferably, the polymerizable composition includes a first component and a second component. The first component comprising (a) a peroxide being compatible or soluble with water, and a (meth)acrylate compound, and the second component includes (b) an aromatic sulfinic acid compound, (c) a tert-amine compound, and (d) water.
