A fan motor according to an embodiment includes a bearing holder, a stator, a circuit board, and a synthetic resin. The stator is mounted at an outer circumference of the bearing holder. The circuit board is electrically connected to a coil of the stator, is mounted at a surface of the base part at an opposite side to the bearing holder, and extends from a base part to a connector housing. The synthetic resin seals the bearing holder, the stator, and the circuit board, except for both end faces of the bearing holder. The connector housing has a gate opening that is injected with the synthetic resin at the time of sealing and ribs that are at an opposite side to the gate opening with the circuit board between the ribs, and tops of the ribs making contact with the circuit board.
