The present invention provides a dust collecting container for an electric dust collector, capable of successfully throwing away the dust without ensuring the dust of a dust collecting container fall obliviously. In the dust collecting container, a filter has a main plane opposite to an outer shell, and a side standing from the end of the main plane to the cross direction of the main plane, a storage part for storing dust formed by the main plane and the side. The storage part forms a dish shape having a bottom, which is formed by the main plane and the side. Thus, in order to throwing away the dust in the storage part, the filter is discharged from the outer shell, even if the storage is not horizontal, the dust in stored in the storage part is obliviously thrown away, throwing away successfully.
