A heat sink-equipped fan motor that is small and flat but superior in heat dissipation or air-cooling effect and that is structurally simple as a whole, easily assembled in thin form and inexpensive. A fan motor (M) comprising a rotor (11) and a stator (12) is mounted on substantially the middle of the plate surface of a base plat (10) adapted to be fixed to various devices requiring heat dissipation. A plurality of thin-sheet-like heat dissipating sheets (17) mutually parallelly stacked with a predetermined clearance therebetween and having an opening (17a) formed in the middle of the plate surface for rotatably receiving the fan motor (M) are used to assemble a heat sink (H) that transfers heat from the base plate (10).
