The plurality of scroll flow paths include a first scroll flow path. The first scroll flow path is configured such that, in a cross section orthogonal to the axial direction of the turbine, an extension line of a line segment connecting the farthest position from the rotation axis of the turbine in an exhaust gas inlet port of the first scroll flow path and the position of a tip of a tongue part formed on the inner circumferential side of the first scroll flow path does not intersect with blades of the turbine.
