PROBLEM TO BE SOLVED: To provide a joined body of hollow ceramic balls which absorbs an impact energy at collision by the crush of the hollow ceramic balls with a relatively small load, and to provide an energy absorbing body which protects the human body by absorbing the energy before the impact at collision increases by using the joined body of the hollow ceramic balls.SOLUTION: The joined body of the hollow ceramic balls is obtained by joining the hollow ceramic balls, and at that time, the ceramic balls are joined with an adhesive. The ratio of the adhesive is 5-50 mass%. |
