Abstract
An anti-electrostatic property between an impeller and a lead wire is improved particularly in a case of a miniature axial flow fan motor. In an axial flow fan motor, an impeller (6) integral with a motor yoke (12) is provided on a shaft (5) rotatably supported by bearings (2,3). An end face of the motor yoke (12) confronted with a PC board (8) mounting a drive circuit and its component parts thereon is covered by resin (P). Resin covering this portion suppresses the generation of the electrostatic current at this portion.
