A power storage device includes a plurality of power storage units which are stacked and disposed in a predetermined direction, a plurality of terminal portions which are provided in the plurality of power storage units, and a plurality of conductive members which extend in the predetermined direction along the plurality of power storage units and are connected to the plurality of terminal portions. Each of the plurality of conductive members includes a connection portion attached to the terminal portion, a main body portion provided integrally with the connection portion, and an electrically insulating coating covering a surface of the main body portion. In each of the plurality of conductive members, a length of the connection portion in the predetermined direction is formed to change with a trend of increasing as a length of the main body portion in the predetermined direction increases.

A stator of a rotary electric machine comprises a stator core, a coil; and a plurality of bus bars. When viewed from a rotational axis direction of the rotary electric machine, the first terminal parts of the plurality of bus bars are arranged next to one another substantially in an upper and lower direction on the outside of the stator core in the radial direction, and the second terminal parts of the plurality of bus bars are arranged next to one another substantially in a horizontal direction above the stator core, and a first terminal part arranged on an uppermost side among the first terminal parts of the plurality of bus bars is arranged to be positioned below an uppermost part of the stator core.

In a wire-connection structure of a motor, bus rings each formed by a bent wire material into a substantially annular shape and arranged along a stator includes: a plurality of large diameter portions and a plurality of small diameter portions extending alternately in a circumferential direction; and a plurality of link portions extending in a radial direction and connecting the adjacent large diameter portion and small diameter portion to each other. Windings of the coils are wire-connected to the link portions. Therefore, it is unnecessary to form the link portions of the bus rings into a U-shape or double-wire overlapping shape, thereby facilitating processing. Moreover, the width of the wire-connection portion in the circumferential direction does not exceed the thickness of a single wire material, thereby facilitating connection work by a crimping tool in a narrow space. Thus, the structure of a crimping portion for fixing by crimping the winding of the coil to the bus ring is simplified, and a space for inserting the crimping tool is secured to improve workability.
