Abstract

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 bodyincludes a first tabular memberconfigured from a ceramic material and having a first thickness t, and a second tabular memberconfigured from a polymer material and having a second thickness t. The laminated bodywithstands 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 tthat is the sum of the first thickness tand the second thickness t
