Among the conventional techniques, the method using the terminal block requires the work of connecting the terminal piece and the coil terminal. The terminal connection work involves matching the lengths of the terminal wires, removing the coating, and joining such as soldering and spot welding. Here, in order to reduce the number of work steps, it is effective to continuously wind the coil, but if the outer diameter of the stator is small or if the number of continuous crossover wires is large, the crossover wire and the terminal wire should be removed. There is a problem that it is difficult to dispose and fix the insulation treatment member in a limited area and to reliably maintain insulation from the lead-out portion of the coil.

An object of the present invention is to provide, for example, a stator for a rotating electric machine or a rotating electric machine which fixes a connecting wire and a terminal wire of a continuous winding coil and establishes reliable insulation between them and a lead-out portion of the coil. Especially.

Further, an object of the present invention is to provide a stator for a rotating electric machine, which is capable of compactly arranging and fixing a connecting wire or a terminal wire to an end portion of a stator even when the number of continuous connecting wires is large. Alternatively, it is to provide a rotating electric machine.
