To realize a radio wave shielding that achieves both low cost and high radio wave shielding performance.SOLUTION: In a radio wave shielding component that allows multiple wire mesh parts to appear to overlap when viewed from a certain direction, a unit shape including an area where no electrical conductor exists and an area where an electrical conductor exists forms an intermediate shape by being repeatedly and adjacently arranged with a first distance as a cycle along the first direction, and the intermediate shapes are repeatedly and adjacently arranged adjacent with a second distance as a cycle along a second direction forming an angle of more than 0 degrees and less than 180 degrees with the first direction to form a wire mesh shape, and two adjacent ones of the plurality of metal mesh portions are arranged to face each other at a third distance corresponding to approximately one fourth of the wavelength of the radio wave to be shielded.SELECTED DRAWING: Figure 1 【課題】低価格性と高い電波遮蔽性能とを両立した電波遮蔽を実現する。【解決手段】ある方向から見た際に複数枚の金網部が重なって見える電波遮蔽部品であって、電気伝導体が存在しない領域と電気伝導体が存在する領域とを含む単位形状が、第１の方向に沿って第１の距離を周期として繰り返し隣接して配置されることによって中間形状を形成し、中間形状が、第１の方向と０度より大きく且つ１８０度より小さいある角度を成す第２の方向に沿って、第２の距離を周期として繰り返し隣接して配置されて、金網形状を成し、複数枚の金網部のうち隣り合う２枚は互いに、遮蔽すべき電波が有する波長の概４分の１に相当する第３の距離だけ離れて対向するように配置される。【選択図】 図１
