Zusammenfassung:	A tip portion of a compressor blade faces a casing with a clearance therebetween. The tip portion has an upstream-side region including a blade leading edge, and a downstream-side region including a blade trailing edge. The upstream-side region has a small clearance formation portion including a part in which the clearance is a minimum in the tip portion. The downstream-side region forms a large clearance formation portion having a clearance larger than a clearance of the small clearance formation portion throughout the entire region of the downstream-side region.
