Abstract: A bonding method includes a step of alternately stacking an electrode foil and a separator and forming a protruding portion extending to extend the stacked electrode foil, and a step of wobbling welding the protruding portion and a collector plate by irradiating an outer surface of the collector plate with laser light in a state in which an inner surface of the collector plate is in contact with the protruding portion.

Abstract: An insulator 5 disposed between a stator core and a three-phase coil wound around the stator core includes a main body section that covers a portion around which the coil is wound in the stator core and insulates the stator core and the coil and a jumper wire holding section 63 that is disposed on a radial direction outer side of the main body section and holds a jumper wire of the coil. The jumper wire holding section 63 includes a first groove 64A in which a jumper wire 3AT of an A-phase coil is housed, a second groove 64B that is disposed on an axial direction other side with respect to the first groove 64A and in which a jumper wire 3BT of a B-phase coil is housed, and a third groove 64C that is disposed on the axial direction other side with respect to the second groove 64B and in which a jumper wire 3CT of a C-phase coil is housed. The first groove 64A, the second groove 64B, and the third groove 64C are formed in different shapes.

Abstract: An insulator 5 disposed between a stator core and a three-phase coil wound around the stator core includes a main body section 61 that covers a portion around which the coil is wound in the stator core and insulates the stator core and the coil, a locking section 62 disposed at an end portion on a radial direction inner side of the main body section 61, and a plurality of jumper wire holding sections 63 that are disposed a radial direction outer side of the main body section 62 and hold jumper wires of the coil. In an axial direction view, at least one of the plurality of jumper wire holding sections 63 is formed shorter in a circumferential direction on the radial direction outer side than in the circumferential direction on the radial direction inner side.
