A dust collecting device and an electric vacuum cleaner capable of: performing centrifugal separation using a swirling flow generated in a cylindrical container body while accumulating centrifugally separated dust; and reliably collecting dust that have once been accumulated. The dust collecting device comprising: a container body 33 having a closed-end cylindrical shape; a suction tube 34 that is connected to the container body 33 and generates a swirling flow along an inner periphery of the container body 33; a discharge tube 35 that is connected to the container body 33 so as to be closer to one end of the container body 33 than the suction tube 34; a partitioning wall 37 that includes a first opening 37a at substantially a center of the container body 33 and is provided between the suction tube 34 and the discharge tube 35; and a separating wall 41 that located closer to another end of the container body 33 than a connection portion of the suction tube 34, forms a gap 39 between an inner peripheral surface of the container body 33 and the separating wall 41, and includes an opening 41a on an outer side of the center of the container body 33. |
