摘要： PROBLEM TO BE SOLVED: To provide a protective member having sufficient protecting performance to a fly object of high penetrating performance such as a bullet, a shell and the like. SOLUTION: In this protective member 1, an impact shock receiving portion 2 is composed of ceramics, and a base portion positioned at a back side of the impact shock receiving portion 2 is composed of a material having coefficient of thermal expansion lower than that of the impact shock receiving portion 2. Thus, such a state that the compressing force is applied to the base portion 3 is kept, and the performance for blocking the penetration of fitted bullet or shell can be improved. Further, as the progress of cracking generated on the impact shock receiving face 2a is stopped at a boundary with the base portion 3, the properties of both materials can be sufficiently exerted, and the protecting performance can be improved by synergistic effect.
