摘要： A laminated body is provided that exhibits impact resistance, wear resistance and scratch resistance, and which enables a reduction in weight together with a reduction in the dielectric constant. The laminated body 100 includes a first tabular member 10 configured from a ceramic material and having a first thickness t1, and a second tabular member 20 configured from a polymer material and having a second thickness t2. The laminated body 100 withstands a falling-ball impact breaking test from a height that is higher than that exhibited by a single layer body that is configured from the ceramic material and of a thickness t3 that is the sum of the first thickness t1 and the second thickness t2.
