Abstract
(EN)
A bus bar (10) which connects the intervals between the terminals (21) of a plurality of power modules (20) arranged in parallel and equipped with a plurality of terminals (21) having screw holes (22) for fixing screws (31) to one surface, and is affixed to the power modules (20) as a result of the alignment of through-holes (13) provided in the bus bar (10) itself with the screw holes (22) and the insertion of the screws (31) through the through-holes (13) and into the screw holes (22), wherein a first thickness of a terminal-contact section for contacting the terminals is thinner than a second thickness in other regions, and the first thickness is a thickness which is capable of deforming in a manner such that the bus bar (10) contact surface which contacts the terminals (21) as a result of the affixing by the screws (31) tightly adheres to the terminals (21).
