1. A co-rotating scroll compressor comprising a driving mechanism, an inverter circuit, a driving scroll, a driven mechanism, a driven scroll, and a housing,
the housing having a suction chamber into which a fluid is suctioned from an outside, an inverter chamber in which the inverter circuit is accommodated, and a partition wall that separates the suction chamber and the inverter chamber from each other,
the driving scroll being disposed in the suction chamber and being rotationally driven around a drive shaft center axis by the driving mechanism,
the driven scroll being disposed in the suction chamber and rotationally following around a driven shaft center axis that is eccentric with respect to the driving scroll by the driving scroll and the driven mechanism,
the driving scroll having a driving end plate extending to cross the drive shaft center axis, and a driving spiral body protruding toward the driven scroll from the driving end plate and forming a spiral shape,
the driven scroll having a driven end plate extending to cross the driven shaft center axis, and a driven spiral body protruding toward the driving scroll from the driven end plate and forming a spiral shape, and
the driving scroll and the driven scroll forming a compression chamber by the driving spiral body and the driven spiral body facing each other, and reducing a volume of the compression chamber by the rotational driving and the rotational following,
wherein a suction port that allows the compression chamber to suction the fluid from the suction chamber is formed in one of the driving end plate and the driven end plate,
the suction port faces the partition wall, and
a discharge port that discharges the fluid from the compression chamber to the outside is formed in the other of the driving end plate and the driven end plate.
