Abstract

A method for manufacturing a compressor scroll that appropriately impinges cavitation bubbles on target regions of a scroll. The method includes the step of water jet peening by jetting cavitation bubbles generated underwater by a water jet at a first side of an end plate (13A) of the scroll (13), with a center (P1, P2, P3) of the cavitation bubbles being offset from a center (O) of the spiral shape of a wall portion (13B) on the end plate (13A) and the step portion (13Aa) and the stepped portion (13Ba) positioned at an outer peripheral portion of the cavitation bubbles (C).
