<p>The present invention relates to a dust collecting apparatus and an electric vacuum cleaner keeping dust, which is separated by a second centrifugal portion, from ascending. The dust collecting apparatus (27) comprises: a first centrifugal portion (90) separating dust in dirty air; the second centrifugal portion (93) connected to the first centrifugal portion (90), separating the smaller dust from the dust which is separated by the first centrifugal portion (90) in the dirty air which passed through the first centrifugal portion (90); a wall portion (161) located opposite to a lower part of the second centrifugal portion (93), inclined toward the lower part of the second centrifugal portion (93), and discharging the separated dust separated by the second centrifugal portion (93) from the lower part of the second centrifugal portion (93); and a dust undercurrent portion (165) divided by the wall portion (161) on a tip side of the wall portion (161) collecting dust induced by the wall portion (161).</p> |
