SOLUTION: An adhesive material is applied to one side face (left side face) of the body core 3 made of highly expanded polystyrene and it is adhered to the inner side of this body 1 on one side (left side). Similarly, the adhesive material is applied to the other side face (right side face) of the body core made of the highly expanded polystyrene and it is adhered to the inner side of the body 2 on the other side (right side). Thus, the left and right bodies 1 and 2 are integrated through the body core 3 and the strong body is obtained.
