Summary:PROBLEM TO BE SOLVED: To provide a radio wave absorbing structure for preventing electromagnetic interference close to within a neighborhood electromagnetic field. SOLUTION: The surface of a radio wave reflection layer, close to a radio wave source, is covered with a radio wave absorbing layer formed by mixing a base material, such as a resin or the like with titanium oxide and conductive carbon black. Here, titanium oxide of 5-40 pts.wt. is mixed with the base material of 100 pts.wt., and the carbon black of 4 pts.wt. or less is mixed with the base material of 100 pts.wt.
