PROBLEM TO BE SOLVED: To provide an electric dust collector and indoor equipment of an air conditioner having this electric dust collector, for forming an optimal constitution to be mounted on the air conditioner, by enabling thickness and weight reduction, by efficiently collecting dust to enhance dust collection efficiency, while providing stable electric charge to the dust.SOLUTION: An electric dust collector is provided with an ionization electrode of high voltage potential on the upstream side of a ventilation flue and a counter electrode of earth potential on the downstream side, and imparts electric charge to dust to collect the dust by electrostatic force. The counter electrode forms a cross-sectional substantially inverse L shape out of a first side part parallel to a flow direction of an air guided to the ventilation flue and having an upstream-side end part and a downstream-side end part and a second side part bent in a direction orthogonal to the direction of the air flow in an air flow downstream side end part of the first side part and the ionization electrode is opposed at a predetermined interval to the air flow upstream side end part of the first side part and the second side part tip of the counter electrode. The counter electrodes are arranged in plurality in parallel with each other with a space part by putting the first side part and the second side part in the same attitude, or are arranged in parallel with each other with the space part by being put in an inverse attitude every other one piece so that the second side part tip is opposed.COPYRIGHT: (C)2014,JPO&INPIT【課題】本実施形態は、塵埃に対して安定した電荷を得るとともに、効率良く集塵できて集塵効率を高め、薄型化および軽量化を可能として、空気調和機に搭載するのに最適な構成をなす電気集塵機およびこの電気集塵機を備えた空気調和機の室内機を提供する。【解決手段】電気集塵機は、通風路の上流側に高圧電位のイオン化電極、下流側にアース電位の対向電極を備え、塵埃に電荷を与えて静電力により集塵し、対向電極は通風路に導かれる空気の流れの方向と平行で、上流側端部と下流側端部を有する第1の辺部と、第1の辺部の空気流れ下流側端部に空気流れの方向とは直交する方向に折曲される第2の辺部とから断面略逆L字状をなし、イオン化電極は対向電極・第1の辺部空気の流れ上流側端部および第2の辺部先端と所定間隔を存して対向し、複数の対向電極を互いに第1の辺部と第2の辺部とを同一姿勢にして空間部を存して並行に配置し
