PROBLEM TO BE SOLVED: To provide a motor fan capable of surely securing a clearance with a rotor while removing remaining bubbles in the inside by seal with a potting material, and its current-currying part shielding method. SOLUTION: The axial-flow fan secures a plane state of a surface opposed to a rotor end surface by a fluororesin-made molding jig in a sealing treatment of a drive circuit by a potting material together with defoaming treatment.
