Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain an electromaganetic wave absorbing material stabled in quality by allocating efficiently dielectiric materials inside an electromagnetic absorbing material in a condition of an averaged and appropriate distribution. SOLUTION: A material for absorbing an electromagnetic wave 30 is formed by solidifying an electromagnetic wave absorbing body 24, which is allocated to disperse internally. This material is produced by burning a material, which the electromagenetic wave absorbing body 24, powdered base materials and foamed materials are combined, in a required temperature, by forming innumerable void parts by foams made internally in a gas originated from a foamed material, and by dispersing the electromagnetic wave absorbing body 24 efficiently and easily to a side wall part 30A surrounding the void parts.
