Claim 0:
1. A centrifugal compressor comprising:
a housing accommodating an impeller;
a diffuser flow path formed radially outside the impeller in the housing; and
a scroll flow path formed in the housing and connected to the diffuser flow path from a radially-outer side, the scroll flow path extending in a rotational axis direction and a rotational direction of the impeller with respect to the diffuser flow path, the scroll flow path including a radially-inner end located at a radially-innermost position, and the radially-inner end being spaced apart from the diffuser flow path with respect to a middle point of a maximum flow path width of the scroll flow path in the rotational axis direction,
wherein a separation distance in the rotational axis direction between the middle point and the radially-inner end is larger in an intermediate section than those at a tongue and at an end of winding of the scroll flow path, the intermediate section being located between the tongue and the end of winding in a direction of extension of the scroll flow path.
