PROBLEM TO BE SOLVED: To provide an environment improving material by which an electromagnetic wave can be decreased satisfactorily without damaging various environment improving functions of charcoal and to provide a structure for improving the environment and a method for improving the peripheral environment. SOLUTION: The environment improving material contains charcoal and ferrite and can be used as a product containing charcoal and ferrite. The structure for improving the environment is characterized in that the environment improving material is arranged to improve the peripheral environment. The method for improving the peripheral environment comprises the steps of: charging the environment improving material and water into a hole bored in the ground; further charging at least one selected from the group consisting of natural salt, crystal, shawl tourmaline, Mitate conglomerate, black silica, apatite and granite porphyry into the hole; and filling up the resulting hole with soil.
