PROBLEM TO BE SOLVED: To provide a stator for a dynamo electric machine which can reduce the possibility of such troubles as dielectric breakdown of a winding or short circuit through a simple arrangement while holding down the production cost low without reducing production efficiency. SOLUTION: A stator 20 arranged concentrically with a rotor rotating about a core axis includes a tubular core member 30 having a plurality of tees on the inner circumferential part, a core holder 50 secured to a case 70 while holding the core member being press fitted along the core axis direction, an insulating member 40 in the shape of a bobbin attached to cover each tee and around which a coil 43 is wound, and a coating member 60 in the shape of a ring provided over the entire circumference of the core member 30 to abut against a part of each outer circumferential surface of the insulating member 40 close to the end face F of the core member 30 on the press fit side, wherein an annular enclosed space P is formed by the core holder 50, the end face F of the core member 30 on the press fit side and the coating member 60 by making the core holder 50 abut against the coating member 60.
