Disclosed is a motor driving device for driving a motor having coil sets that includes energization systems each including a drive circuit, the drive circuits being one-to-one connected to the coil sets; first semiconductor switches disposed in the energization systems in a one-to-one correspondence, each first semiconductor switch lying between a power supply and the corresponding one of the drive circuits; and a second semiconductor switch which connects the power supply and each of the first semiconductor switches in series. Each of the first semiconductor switches includes a parasitic diode of which a forward direction is from the corresponding drive circuit to the second semiconductor switch, and the second semiconductor switch includes a parasitic diode of which a forward direction is from the power supply to the first semiconductor switches.
