<p>A bus bar (70) is used in a power conversion apparatus (100), which has a first switching element (1H) as an upper arm, and a second switching element (1L) as a lower arm connected in series, and which supplies power to a load (3) by converting a voltage and a current supplied from a direct current power supply (2). The bus bar has: a high potential electrode (Ep) that connects together the high potential side of the direct current power supply and the positive electrode side of the first switching element; a low potential electrode (En) that connects together the low potential side of the direct current power supply and the negative electrode side of the second switching element; and an insulating layer (71). A part of the high potential electrode and a part of the low potential electrode overlap each other with the insulating layer therebetween. A snubber circuit (40) is electrically connected between the high potential electrode and the low potential electrode.</p> |
