PROBLEM TO BE SOLVED: To provide a vacuum cleaner hardly reducing the suction force while securing a high suction force. SOLUTION: The vacuum cleaner includes suction port (not illustrated) for introducing air including dust sucked by an electric blower (not illustrated), and a dust collection case 5 set on the upstream side of the electric blower for collecting duct. The dust collection case 5 includes a dust separating part (not illustrated) for separating dust, a dust storage part 24 for storing the separated dust, and a filter (not illustrated) for filtering out dust. The dust storage part 24 includes an air intake 34 for preventing the dust from swirling by generating a swirling air flow different from a main air pathway (not illustrated) for air from the suction port, passing through the dust separating part and through the filter. When dust is carried to the dust storage part 24, the swirling air flow of sucked air passing through the air intake 34 prevents the dust from continuously swirling within the dust storage part 24 and swirling up to the dust separating part, and prevents the dust within the dust storage part 24 from re-adhering to the filter, so that the reduction of the air volume can be suppressed.
