PROBLEM TO BE SOLVED : To provide a polymerizable composition and a resin molded product useful for production of a laminate having a high dielectric constant, low dielectric loss tangent, small rate of change in a dielectric constant due to temperature, and also excellent mechanical strength, heat resistance, and crack resistance in a cold-heat shock test, the laminate, and further a dielectric device obtained by using the laminate.
SOLUTION : The polymerizable composition contains a cycloolefin monomer, a polymerization catalyst, a crosslinking agent, a crosslinking aid, and composite dielectric ceramics represented by composition formula {Ba6-3x[(La1-wREw)1-yBiy]8+2x}zTi18O36+18z, wherein 0.28≤w≤0.99, 0.5≤x≤0.9, 0.1≤y≤0.27, 0.8≤z≤1.2, and RE is a rare earth element other than La. The resin molded product is obtained by polymerizing the polymerizable composition. The laminate is obtained by laminating the resin molded product and the resin molded product and/or another substrate material and then curing the same. The dielectric device is obtained by using the laminate.
