A spindle motor includes a base portion, a rotor hub, a stator, and a circuit board. The base portion preferably includes a through hole and is arranged to spread out radially around a central axis. The rotor hub is arranged above the base portion to rotate about the central axis. The stator is arranged above the base portion, and includes coils each including at least one lead wire. The circuit board is arranged radially outward of the through hole, and arranged on a lower surface of the base portion. The base portion includes a communicating groove arranged to join the through hole and the circuit board to each other. The at least one lead wire of the coils is arranged to pass inside the through hole and the communicating groove to be electrically connected to the circuit board. The through hole is sealed with a sealant.
