PROBLEM TO BE SOLVED: To provide a three-phase dynamo-electric machine having three-phase distributed windings and its manufacturing method. SOLUTION: A U-phase coil 24U is a coil previously formed with a shape in which a copper wire is sequentially wound onto a square pyramid trapezoid in line, and sequentially inserted into a slot of a stator core in order of short circumference length. A V-phase coil 24V is a coil previously formed with a shape in which a copper wire is sequentially wound onto a square pole in line, and sequentially inserted into the slot of the stator core. A W-phase coil 24W is a coil previously formed with a shape in which a copper wire is sequentially wound onto a square pyramid trapezoid as a reverse of the square pyramid trapezoid of the first phase in line, and sequentially inserted into the slot of the stator core in order of long circumference length.
