To provide a conveyance device capable of controlling speed of a conveyance means driven by electric power with high precision.

This conveyance device 1 detects travel amount of a movable piece 20 driven by a linear motor and moving linearly by a rotary encoder RE and compensates a torque command and/or speed error in a predetermined position cycle by a compensation means for compensating fluctuation in the predetermined position cycle calculated by FFT-operating the torque command and/or speed error to control conveyance. This conveyance device 1 is povided with a filter for performing averaging processing when calculating the compensated value to prevent influence by unforeseen fluctuation.
