Abstract: A flat wire (36) that forms a stator coil (16) has an insertion portion (22) that is inserted into a slot (14), and a coil end portion (30) that protrudes from an end portion of the stator coil (16). An insulating layer of an adjacent portion (38) that is adjacent to a flat wire (36) of a different phase at the coil end portion (30) is thicker than an insulating layer in another region. Setting the thickness of the insulating layer of each part according to the required insulation performance in this way makes it possible to make the overall insulating layer thinner, and improve the in-slot space factor of the stator coil while ensuring insulation performance.

Abstract: A slot insulating paper (12) is arranged in a slot (18) of a core (10) of an electric motor or generator. In a state where the slot insulating paper (12) is spread in a sheet shape, a region (high stiffness portion (36)) that is part of the slot insulating paper (12) is a breakage resistance portion having a higher resistance against breakage than the other region (ordinary portion (38)).

In the breakage resistance portion, for example, at least one of the laminated insulating layers is a high stiffness layer formed of a high stiffness material. Thus, the breakage resistance portion is formed to have a high stiffness. With a high stiffness, it is possible to improve breakage resistance.
