Abstract
A stator includes a stator core, and a coil mounted on the stator core and having an insulating film, at least a part of the insulating film being coated with a protective paint, wherein the insulating film has a vacancy, and the vacancy is formed by a hollow capsule. In addition, the protective paint has a powder, and an internal form of the vacancy is smaller than an external form of the powder.
