An electric vacuum cleaner including a suction tool main body, a vacuum cleaner main body which communicates to the suction tool main body, and a dust collector provided at the vacuum cleaner main body. The dust collector includes a dust collection container, a tubular body disposed at substantially a central portion of the dust collection container in a vertical direction, a collar portion which is formed to project towards an inner wall on the dust collection container, vent holes which are piercingly provided at the tubular body, and an intake which opens at the dust collection container. The flow passage of air which extends from the central portion of the tubular body on a bottom portion of the dust collection container to the vent holes can be made long so that it is possible to exhibit the effect that the amount of stirred up dust reaching the vent holes can be reduced.
