PROBLEM TO BE SOLVED: To prevent beauty of a periphery of an electrode from being spoiled by dirt.SOLUTION: An air cleaning unit includes: a charging part (40) that electrifies dust in air a dust collecting part (60) which is arranged in the downstream of the charging part (40) in a flow of air to be processed having passed through the charging part (40) and collects the electrified dust a power supply member (61) which is configured of metal and supplies a first potential and a conductive member (66). The dust collection part (60) has a high-voltage electrode (71) configured of a resin having conductivity and a dust collection electrode (81) to which a second potential lower than the first potential is supplied. The conductive member (66) is configured of non-metal, has volume resistivity lower than that of the high-voltage electrode (71), and is held between the power supply member (61) and the high-voltage electrode (71).COPYRIGHT: (C)2016,JPO&INPIT【課題】電極の周辺の美観が、汚れによって損われないようにする。【解決手段】空気清浄ユニットは、空気中の塵埃を帯電させる荷電部(40)と、上記荷電部(40)を通過した被処理空気の流れにおいて上記荷電部(40)の下流に配置され、帯電した塵埃を捕集する集塵部(60)と、第1電位を供給する、金属で構成された給電部材(61)と、導電性部材(66)とを有する。上記集塵部(60)は、導電性を有する樹脂で構成された高圧電極(71)と、上記第1電位より低い第2電位が供給される集塵電極(81)とを有する。上記導電性部材(66)は、非金属で構成され、体積抵抗率が上記高圧電極(71)の体積抵抗率より低く、上記給電部材(61)と上記高圧電極(71)との間に挟まれている。【選択図】図4
