The present invention is devised to allow accurate determination on quality of a current sensor, and provide a current sensor reduced in size and cost and an inverter having the current sensor. A direct-current sensor 380 detects direct currents supplied to a plurality of inverters 300 and 301 for driving an alternating-current motor 200 in which winding wires of a stator are independent from each other in individual phases and a voltage is individually applied to the independent winding wires. The plurality of inverters has a P connecting wire 150 connecting P buses and an N connecting wire 160 connecting N buses. The direct-current sensor 380 has a core surrounding the P connecting wire and the N connecting wire to detect the currents flowing into and out of the P bus and the N bus. This makes it possible to employ a small-capacity current sensor, improve the sensor accuracy, and allow accurate determination on the quality of the current sensor.
