A highly reliable resin-molded stator not suffering insulation breakdown between the different phases of the stator coils even when the operation mode where the output of a rotary machine using a resin-molded stator in which a stator coil wound around a plurality of slots and a stator coil provided at the stator core end are resin-molded is to be increased from the level under a stopped status to the maximum achievable level within a short time is repeated. Also disclosed is a method of manufacturing such a stator, and a rotary machine using the same. The resin-molded stator of the present invention comprises a stator core, electrically insulated stator coils wound around the plurality of slots or protrusions provided in the axial direction of the stator core, and molding resin with which are molded the stator core and the stator coils located at the aforementioned slots or protrusions and at the stator core end, wherein the resin-molded stator is characterized in that non-adhesive structure is established between the molding resin and at least one of the end faces of the stator core.
