Abstract
To prevent varnish from adhering to an adhesion prohibited area while satisfying required performance for varnish. A method for manufacturing a stator of a rotating electric machine in which a coil is wound around a stator core, the method includes: a first varnish process of forming a first varnish portion by dropping varnish at a coil disposed on an outermost circumference or an innermost circumference of a coil end portion where the coil protrudes from the stator core and positioned close to the stator core; and a second varnish process of forming a second varnish portion to provide a non-existence region where varnish is not applied between the first varnish portion and the second varnish portion by dropping varnish at a position farther from the stator core than a position in the first varnish process.
