摘要： The present invention provides a rotary electric machine, of which the occupied volume can be reduced and which allows a space in an electric apparatus equipped therewith to be utilized effectively. A slot insulator 15 is integrally formed with a holder mounting portion 25, a whole or major part of which is positioned on one of end faces of a yoke 11 of a stator core 7. A lead wire holder 27 includes a connection holding portion 27a for disposing a plurality of connections 30, in which lead-out wires of windings are connected with corresponding core wires 29a of lead wires 29, at a predetermined interval so that the connections do not contact with each other. The lead wire holder 27 is arranged so that the connection holding portion 27a is positioned over a part of the windings 9 and the holder mounting portion 25 when the lead wire holder is attached to the holder mounting portion 25. One end bracket, which faces to one of the end faces of the yoke, is formed with a recess which opens toward both sides in the axial direction thereof as well as opens outwardly in a radial direction of a shaft. The holder mounting portion 25 and lead wire holder 27 are received within the recess when the one end bracket is attached to the one end face of the yoke.
