PROBLEM TO BE SOLVED: To obtain a method for manufacturing an electromagnetic wave absorbing board, capable of imparting an electromagnetic wave antireflection function to a slope surface or a vertical wall surface and growing a plant. SOLUTION: The method for manufacturing the electromagnetic wave absorbing board 10 comprises the steps of forming a plurality of granular intermediate particles, in which a core material is covered with a coating solution, in which an electromagnetic wave absorbing heating material is dispersedly mixed with the solution to be mixed, and solidifying the solution to be mixed of each intermediate particle, in a state in which a plurality of the particles are made to contact, and thereby molding the solution in a plate-like state in which air gaps 12 are formed. Here, the absorbing board 10 is installed on the normal or the wall surface. Thus, the electromagnetic wave absorbing heating material in the board 10 absorbs electromagnetic waves, and the antireflection function can be imparted to the normal or the wall surface. Furthermore, since a polymer 28 is filled in air gaps 12 of the board 10 and the heating material absorbs the wave and heats, a moisture can be stably supplied to the plant on the board 10, the heating material can heat and growing of the plant can be promoted. |
