To provide a charging apparatus that can tear off dust adhering to an earth electrode by self purification.SOLUTION: A charging apparatus 10, which electrically charges dust included in dust-containing air by corona-discharge while circulating the dust-containing air, comprises a plurality of discharging electrodes 71 supported on a support body 70 and earth electrodes 60, provided, across gaps G for causing the corona discharge, between the discharging electrodes 71 respectively, which have a plurality of circulation holes H through which the dust-containing air circulated through the gaps G is passed. The earth electrode 60 includes a plurality of inclined surface parts F1 faced with the plurality of gaps G and inclined with respect to a circulating direction of the dust-containing air that enters the gaps G.SELECTED DRAWING: Figure 4 【課題】接地電極に付着した塵埃を自浄作用によって引き剥がすことができる帯電装置を提供する。【解決手段】含塵空気を流通させながらコロナ放電によって含塵空気に含まれた塵埃を帯電させる帯電装置１０であって、支持体７０に支持されている複数の放電用電極７１と、各々の放電用電極７１との間にコロナ放電を発生させるための隙間Ｇを挟んで設けられ、各々の隙間Ｇを流通した含塵空気を通過させる複数の流通穴Ｈを有する接地電極６０と、を備え、接地電極６０は、複数の隙間Ｇに面して隙間Ｇに進入する含塵空気の流通方向に対して傾斜した複数の傾斜面部Ｆ１を含んでいる。【選択図】図４
