Stator and manufacturing method of the same

A manufacturing method configured to be installed in a stator of a rotary electric machine, the method comprising:

• inserting segment conductors respectively into slots formed in a stator core having a hollow cylindrical shape;
• bending a first end portion and a second end portion of the segment conductors which protrude from an end surface of the stator core so as to arrange conductor joint portions in both of a circumferential direction and a radial direction of the stator core, the conductor joint portions comprising the first and second end portions of the segment conductors;
• temporarily attaching a sensor unit between a first segment conductor and a second segment conductor that constitute one of the conductor joint portions, the sensor unit comprising a sensor holding conductor and a temperature sensor;
• and
• welding the conductor joint portions individually so as to form a stator winding with the segment conductors, the welding comprising:
• welding the first segment conductor and a first segment of the sensor holding conductor to each other;
• and
• welding the second segment conductor and a second segment of the sensor holding conductor to each other,
• wherein the temperature sensor is attached to the first segment and the second segment.
