PROBLEM TO BE SOLVED: To provide a polymerizable composition useful for manufacturing of a layered product having a high relative dielectric constant and a low dielectric loss tangent, small temperature variation of the relative dielectric constant and being excellent in heat-resistance and anti-crack property at a cold heat impact test, a prepreg, a layered product and a dielectric body device using the layered product. SOLUTION: The polymerizable composition contains a cycloolefin monomer, a polymerization catalyst, a crosslinking agent, crosslinking auxiliaries, and a high dielectric filler comprising a combination of a zirconium oxide and a titanium oxide. The prepreg obtained by polymerizing the polymerizable composition after a reinforced fiber is impregnated with it, the layered product obtained by stacking the prepreg on the prepreg and/or the other material and curing it, and the dielectric body device using the layered product are provided.
