To improve control characteristics of an inverter while suppressing manufacturing cost. An inverter control device 10 is a device for controlling an inverter device 1 having a plurality of switching elements. The inverter control device 10 includes a current control unit 13 that calculates three phase voltage command signals Vu*, Vv*, and Vw* based on a d-axis current command signal id* and a q-axis current command signal iq* at each predetermined calculation period T0, a sampling period conversion unit 14 that outputs three phase voltage command signals Vu**, Vv**, and Vw** after update at each predetermined update period T1 different from the calculation period T0 based on a calculation result of the three phase voltage command signals Vu*, Vv*, and Vw* by the current control unit 13, and a gate signal generation unit 15 that generates a gate signal for switching-driving a plurality of the switching elements based on the three phase voltage command signals Vu**, Vv**, and Vw** after update output from the sampling period conversion unit 14.
