PROBLEM TO BE SOLVED: To provide a vacuum cleaner capable of preventing decline of the suction force by preventing fine dust stored in a fine dust chamber from being stirred up by air currents to adhere to a filter again. SOLUTION: The vacuum cleaner includes a first dust separating means 36 for separating rough dust from air, a second dust separating means 37 (the filter) for separating fine dust from air, and the fine dust chamber 32 disposed under the second dust separating means 37 (the filter) for storing fine dust separated by the second dust separating means 37 (the filter). The vacuum cleaner also has a sideways stirring air current blocking means disposed near the fine dust chamber 32 for blocking the air current in the direction crossing a suction air pathway into an electric fan 21. With this structure, the quantity of dust stored in the fine dust chamber 36 to be stirred up to adhere to the second dust separating means 37 (the filter) can be reduced, and decline of the sucking capability caused by the clogging of the second dust separating means 37 (the filter) can be prevented.
