1. A turbocharger comprising:
an impeller which includes a hub provided to be rotatable around a center axis and a plurality of turbine blades arranged on the outside of the hub in a radial direction at intervals in a circumferential direction around the center axis; and
a turbine housing which is disposed on the outside of the impeller in the radial direction and forms a scroll flow path guiding an exhaust gas toward the impeller on the inside of the radial direction while turning the exhaust gas in the circumferential direction,
wherein a flow path width in the circumferential direction of at least one of a plurality of inter-blade flow path portions formed between the plurality of turbine blades is different from a flow path width of another of the plurality of inter-blade flow path portions wherein a radial dimension of the hub of a first of the plurality of inter-blade flow path portions is larger than a radial dimension of the hub of a second of the plurality of inter-blade flow path portions having a larger flow path width than that of the first of the plurality of inter-blade flow path portions.
