PROBLEM TO BE SOLVED: To provide an indoor unit for an air conditioner in which negatively charged dust is easy to be sucked to a fin of a heat exchanger.SOLUTION: An indoor unit of an air conditioner of the embodiment includes: a negative ion generator which is provided on a downstream side of an air filter in a ventilation flue, which has a negative ion electrode to which a high voltage of a minus potential is applied, and which negatively charges the dust in the air flowing in the ventilation flue; and a heat exchanger which is provided on the downstream side of the negative ion generator in the ventilation flue, which is configured by a tabular fin having electric conductive properties, and to which earth potential is applied as a counter electrode of the negative ion generator and which exchanges heat with the air flowing in the ventilation flue. The negative ion electrode has an electrode needle part protruding in a triangular shape, and in which a direction of a bisector for bisecting a tip part of the electrode needle part is inclined with respect to a normal direction of the fin.SELECTED DRAWING: Figure 4 【課題】マイナス電位に荷電した塵挨類が熱交換器のフィンに吸引され易くなるようにした空気調和機の室内機を提供する。【解決手段】本実施形態に係る空気調和機の室内機は、通風路中にあってエアフィルタの下流側に設けられ、マイナス電位の高電圧が印加されるマイナスイオン電極を有し、通風路内を流れる空気中の塵挨類をマイナス電位に荷電するマイナスイオン発生器と、通風路中にあってマイナスイオン発生器の下流側に設けられ、導電性を有する板状のフィンで構成されており、マイナスイオン発生器の対向電極としてのアース電位が印加されるとともに、通風路を流れる空気と熱交換する熱交換器と、を備えており、マイナスイオン電極は、三角形状に突出する電極針部を有しており、電極針部の先端部を二等分する二等分線の方向がフィンの法線方向に対して傾斜している。【選択図】図４
