A compressor housing accommodating a compressor wheel for compressing intake air supplied to an engine has therein an outer cooling passage extending along a circumferential direction on an outer circumferential side of a scroll passage of a spiral shape through which the intake air compressed by the compressor wheel flows, and an inner cooling passage extending along the circumferential direction on an inner circumferential side of the scroll passage. The inner cooling passage is separated from the outer cooling passage by a separation wall extending along the circumferential direction.
