A centrifugal compressor comprising: a first splitter blade (7) disposed on the side close to the negative pressure surface (Sb) of a full blade (5F) on the upstream side in the compressor rotation direction; and a second splitter blade (8) disposed on the far side of the negative pressure surface (Sb) of the full blade (5F) and which is shorter than the first splitter blade. The centrifugal compressor is characterized by the front edges (7a, 8a) of the shrouds of the first splitter blade (7) and the second splitter blade (8) being closer to the negative pressure surface (Sb) side of the full blade than to positions at intervals between the full blades equally divided by the number of splitter blades. |
