<P>PROBLEM TO BE SOLVED: To provide a diffuser for a compressor, improving the compression efficiency of the compressor such as a barrel compressor without increasing a pressure loss by a simple structure. Ž<P>SOLUTION: In each diffuser 2 for the compressor, each diffuser vane 4 is provided along a swirl flow S of compressed gas in a diffuser disk 3, and a gas channel 5 is formed between the vanes 4. The downstream side of the diffuser vane 4 extends continuously along the outside shape of each diffuser vane 4. In the plan view of the longitudinal section of the compressor including an axis C, the extended diffuser vane 4 has a curved portion 4b to be terminated immediately before the compressed gas is directed to an outlet channel 8.
