Claim 0:
1. A laminated bus bar for use in a power converter capable of bidirectional power conversion, the laminated bus bar comprising:
a flat plate portion having a length direction, a width direction orthogonal to the length direction, and a thickness direction orthogonal to the length direction and the width direction,
the flat plate portion including
a first conductive plate having a first AC terminal and a second AC terminal,
a second conductive plate having a first positive DC terminal and a second positive DC terminal,
a third conductive plate having a first negative DC terminal and a second negative DC terminal, and
first to fourth insulating plates alternately stacked in the thickness direction for the first to third conductive plates, wherein

the flat plate portion has a first end portion in the length direction of the flat plate portion and a second end portion on an opposite side to the first end portion,
in the first end portion,
the first AC terminal protrudes from the first conductive plate in the length direction,
the first positive DC terminal protrudes from the second conductive plate in the length direction,
the first negative DC terminal protrudes from the third conductive plate in the length direction, and
the first AC terminal, the first positive DC terminal, and the first negative DC terminal are arranged in alignment in this order from a third end portion in the width direction of the flat plate portion toward a fourth end portion on an opposite side to the third end portion, and

in the second end portion,
the second AC terminal protrudes from the first conductive plate in the length direction,
the second positive DC terminal protrudes from the second conductive plate in the length direction,
the second negative DC terminal protrudes from the third conductive plate in the length direction, and
the second AC terminal, the second negative DC terminal, and the second positive DC terminal are arranged in alignment in this order from the third end portion toward the fourth end portion of the flat plate portion.
