The present invention provides an electric dust collector capable of always keeping optimal attractive force for various kinds of dust, thereby improving the control precision and efficiency of the power supplied to the electric blower fan. The electric dust collector of the present invention comprises a first dust detecting device(35); a second dust detecting device(36); a first holding device(37)for giving holding time to each signal and outputting a first holding signal based on the first dust detecting signal detected by the first dust detecting device; a second holding device(38)for giving holding time to each signal and outputting a second holding signal based on the second dust detecting signal detected by the second dust detecting device; and a display control device(14)for controlling the power supplied to the electric blower fan based on the first holding signal and the second holding signal. Thus, the dust of different sizes can be detected according to various sizes of thedust respectively so as to improve the control precision of the power according to the size, the kinds and the quantity of dust.
