A drive device includes a shaft, a rotor, a stator, a bearing, a housing, a first neutralizing device, and a seal member. The shaft extends in the axial direction along a rotation axis. The rotor is fixed to the shaft and is rotatable about the rotation axis. The stator faces the rotor with a gap therebetween in the radial direction. The bearing rotatably supports the shaft. The housing accommodates the rotor, the stator, and the bearing. The first neutralizing device is arranged on one axial side of the bearing and electrically connects the shaft and the housing. The seal member is arranged between the bearing and the first neutralizing device in the axial direction.
