In a disclosed electric dust-collecting unit, needle electrodes (11) face laterally against openings, so that a person in charge of replacement or maintenance/inspection of the electric dust-collecting unit can be prevented in safety from being injured on his fingers or body by needles. Therefore, this type of the electric dust-collecting unit can be applied in an air cleaner not only in offices but also in homes. In addition, this type of the electric dust-collecting unit does not employ a conventional box-pillar type needle support, so that its air flow path is not suppressed with a resultant remarkable decrease in a pressure loss, thus contributing to compacting of the electric dust-collecting unit and hence the air cleaner. <IMAGE> |
