上げることができる。The raised concrete cast by the method of the above embodiment and which constitutes the base of the 72PC plate has water permeability and is easily impregnated with other fluids, so the polymer mixed with the ferrite powder is mixed into the raised concrete. Ferrite, which is easily impregnated and integrated with the concrete and mixed into the polymer, can widen the particle size distribution conditions and increase the mixing ratio.

A method is also used in which the central part of the concrete is filled with ferrite and only the layer layer is impregnated with polymer mixed with ferrite, or the central part and inside of the raised concrete is filled with ferrite and only the surface layer is completely impregnated with polymer. By any of the methods, a PC plate having radio wave absorption performance can be manufactured.
