Abstract
A bus bar connection structure includes a housing, a circuit board including metal, and a bus bar that are disposed in order from a lower side, a lower nut including metal and disposed in an upper surface-side of the housing in a state in which the lower nut is embedded in the housing, and a bolt including metal. On an upper surface of the circuit board, an insulation layer and a copper foil pattern are formed in order from a lower side. An insulation paper piece is disposed between the lower nut and the circuit board. The bolt is screwed into the lower nut in a state in which the bolt is inserted through the insulation paper piece, the circuit board, the insulation layer, the copper foil pattern, and the bus bar. A rotation-preventing part is further provided, the rotation-preventing part preventing the insulation paper piece from rotating due to torque generated during fastening of the bolt.
