PROBLEM TO BE SOLVED: To provide a radio shielding body which can selectively shield two kinds of radio waves with different frequencies by a high shield factor. SOLUTION: A plurality of first antennas 4 for each reflecting the radio wave with first frequencies, and a plurality of second antennas 5 for each reflecting the radio wave with second frequencies are provided in the radio shielding body 1 in such a manner as to constitute a pattern. The first antenna 4 and the second antenna 5 are different in size from one another. The first antenna 4 and the second antenna 5 comprise first three segment-like element parts with almost the same length, which are elongated outward from the centers of the antenna by making an angle of 120°with one another, and second segment-like element parts with almost the same length as that of the first element part, which are provided at the respective outside ends of the first three element parts and the centers of which are connected together in such a manner as to be orthogonal to the first element parts.
