Abstract:
A spindle motor according to an embodiment includes a base plate, a rotor magnet fixed to a rotor assembly positioned at one surface side of the base plate and a magnetic attraction plate fixed at the one surface side of the base plate so as to face the rotor magnet. An opposite area of the base plate facing the magnetic attraction plate includes a coated area covered by an epoxy electric discharge coating film, and the magnetic attraction plate is fixed to the opposite area via at least one of an epoxy adhesive and an acrylic adhesive.
