Claim:
1. A power conversion apparatus comprising: a semiconductorelement; a cooler cooling the semiconductor element; a circuit board electrically connected to the semiconductor element; and a laminated bus-bar electrically connected to the semiconductor element, with the semiconductor element and the laminated bus-bar being disposed above the cooler, and the circuit board being further disposed above the semiconductor element and the laminated bus-bar, to exhibit a power converting function by a switching operation of the semiconductor element, wherein the laminated bus-bar has a configuration in which plate-like bus-bars are laminated via an insulating material to define a pair of bus-bars, and the pair of bus-bars is disposed vertically so that a width thereof is set in a vertical direction, and wherein the laminated bus-bar includes a pair of voltage measuring terminals that is correspondingly branched from a part of the pair of bus-bars to extend toward the circuit board to be electrically connected thereto, the pair of voltage measuring terminals respectively having projecting portions and upright portions, the projecting portions of the pair of voltage measuring terminals respectively projecting from opposite surfaces of the laminated bus-bar, and the upright portions of the pair of voltage measuring terminals respectively extending from respective ends of the projecting portions upwards towards the circuit board.
