Zusammenfassung:PROBLEM TO BE SOLVED: To provide a vacuum cleaner capable of reducing noise without decreasing air capacity.SOLUTION: A vacuum cleaner includes: a motor case set 20 including an electric blower 21 for generating suction force, and a storage case 22 for storing the electric blower 21; a dust collection part 7 for collecting dust; an air intake duct 30 for leading the air from the dust collection part 7 to an air intake port 22c of the motor case set 20; and a housing for accommodating the motor case set 20 together with the air intake duct 30. The air intake duct 30 is provided with an introduction port 31 for introducing the air from the dust collection part 7 in a direction that intersects with the axial direction of a rotation axis 21a. A control board 40 is arranged between the air intake duct 30 and the housing 10 in a position corresponding to the air intake port 22c so as to approach the air intake port 22c from the introduction port 31 toward the air intake port 22c. 【課題】風量を減少させずに騒音を低減することが可能な電気掃除機を提供する。【解決手段】吸引力を発生する電動送風機21と、当該電動送風機21を収容する収容ケース22と、を含むモーターケース組20と、塵埃を集塵する集塵部7と、集塵部7からの空気をモーターケース組20の吸気口22cに導く吸気ダクト30と、吸気ダクト30とともにモーターケース組20を収容する筐体と、を備え、吸気ダクト30には、回転軸21aの軸方向に対して交差する方向に集塵部7からの空気を導入する導入口31が設けられ、吸気口22cに対応する位置において、吸気ダクト30と筐体10との間に、制御基板40を、導入口31から吸気口22cに向けて当該吸気口22cに近づくように配置した。【選択図】図3
