A centrifugal compressor includes a compressor impeller, a motor, an inverter, a housing including a motor chamber and an inverter chamber, a conductive member, an insertion hole, and a resin member sealing the insertion hole. A pressure in the motor chamber is higher than that in the inverter chamber. The resin member includes a first resin portion fixed to the housing and a second resin portion which is covered with the first resin portion and which covers the conductive member, the second resin portion having a Young's modulus smaller than that of the first resin portion. The first resin portion and the second resin portion, and the second resin portion and the conductive member are coupled by insert-molding.
