ABSTRACT:
To provide an inverter unit with excellent manufacturing performance and with current carrying capacity increased and size reduced by further increasing the cooling efficiency of a power efficiency device.The inverter unit includes: a semiconductor chip constituting an arm of an inverter; a first conductor33joined to a positive side of the semiconductor chip; and a second conductor35joined to a negative side of the semiconductor chip. The first and second conductors are disposed above a cooler22cooling the semiconductor chip so that a joint surface of the first conductor33which is joined to a positive electrode of the semiconductor chip and a joint surface of the second conductor35which is joined to a negative electrode of the semiconductor chip are not in parallel to a surface of the cooler22.
