PROBLEM TO BE SOLVED: To provide: a defogger capable of reducing electromagnetic noise irradiated from a heating coil and having high electromagnetic noise reduction effects; and a window pane including the defogger.SOLUTION: A defogger placeable on a window pane includes a reciprocating heating coil. An outward path and a return path of the heating coil are adjacent to each other with a distance at which mutual induction occurs. A window pane includes the defogger. For example, it is preferable to establish d<√(2×a×b/e), where a is a radius of the heating coil, b is a length that the outward path and the return path lie in parallel, e is Napier's number, and d is a distance between the center of the outward path in a line width direction and the center of the return path in the line width direction.SELECTED DRAWING: Figure 1
【課題】熱線から放射される電磁ノイズを低減でき、その低減効果の高い、デフォッガ及び該デフォッガを備える窓ガラスを提供すること。【解決手段】窓ガラスに設置可能なデフォッガであって、往復する熱線を備え、前記熱線の往路と復路は相互誘導が発生する間隔で近接する、デフォッガ及び該デフォッガを備える、窓ガラス。例えば、前記熱線の半径をa、前記往路と前記復路とが並走する長さをb、ネイピア数をe、前記往路の線幅方向の中心と前記復路の線幅方向の中心との距離をdとすると、d<√(2?a?b/e)が成立することが好ましい。【選択図】図1
