    摘要: An object of the present invention is to suppress an outflow of varnish from a lower portion of a stator core by increasing a filling rate of varnish in a slot. Provided is a method for manufacturing a stator of a rotary electric machine. The stator has a coil and a stator core in which a slot that houses the coil is formed, and a resin member of which viscosity is low at a first temperature and the viscosity is high at a second temperature higher than the first temperature is filled in the slot from an injection side. The manufacturing method includes a first step of causing a temperature difference in the stator core such that the injection side becomes the first temperature and an opposite side of the injection side becomes the second temperature, and a second step of injecting the resin member from the injection side in a state in which the temperature difference is maintained.
