A blower apparatus 100 in which power supply voltage Vig from a battery 70 is supplied to a power supply input terminal Tv1 through a power supply switch 71 of which on-off control is made according to a state of an ignition switch of a vehicle, comprising a motor 13 having a stator 11 with a coil 16 wound therearound and a rotor 12 disposed rotatably about a rotation shaft; a blowing fan 103 on the rotation shaft 20; a motor drive circuit 35 for electrically driving the coil 16; a microprocessor 34 for controlling the motor drive circuit 35; a motor case 14 integrally containing the motor 13, the motor drive circuit 35, and the microprocessor 34; an internal power line 32 for supplying the power supply voltage Vig applied to the power supply input terminal Tv1 to the motor drive circuit 35 and the microprocessor 34 in the motor case 14; a smoothing capacitor 33 connected to the internal power line 32; a cut off control circuit 38 for cutting off supply of the power supply voltage Vig to the internal power line 32 according to a command from the microprocessor 34, wherein the cut off control circuit 38 makes the power supply switch 71 turn off to cut off supply of the power supply voltage to the internal power line 32, which causes the microprocessor 34 and the motor drive circuit 35 to be in an inoperable state.
