<p>A radio wave shielding body (1) has antennas (4) each reflecting a radio wave of a specific frequency. The antennas (4) are arranged so as to form a pattern. Each of the antennas (4) has three segment-like first elements (4a) and three segment-like second elements (4b). The three first elements (4a) extend radially from the center of the antenna (4) by substantially the same length with 120º apart from each other. Each of the second element sections (4b) is joined to the outer end of each first element section (4a).</p>
