<p>An elevator control device according to an embodiment of the invention comprises: a control drive unit (2); an inverter unit 5 (3); a cooling fan (8) that delivers a current of cooling air to this inverter unit (3); a regenerative resistor unit (5) arranged above the control drive unit (2) and wherein a plurality of regenerative resistors (4) are arranged in a plurality of levels therein in the vertical direction; a first exhaust port (9) whereby 10 the current of cooling air from the cooling fan (8) is fed to the regenerative resistor unit (5); and a second exhaust port (10) provided in the regenerative resistor unit (5) and whereby the current of cooling air delivered from the cooling fan (8) is discharged to the outside; wherein: the regenerative resistors (4) 15 are arranged so as not to overlap with the location of arrangement of the cooling fan (8) on a projection area from above and at least some of the second exhaust ports (10) are arranged in the regenerative resistor unit (5) so as to overlap with the location of arrangement of the regenerative resistors (4) on a projection 20 area from the front face.
