Zusammenfassung:PROBLEM TO BE SOLVED: To improve efficiency of an impeller of a multistage centrifugal com pressor by reducing frictional loss and to easily manufacture it at low cost. SOLUTION: An impeller for a multistage centrifugal compressor is constituted of a core plate 3, a side plate 2 and a plural number of vanes 10 arranged between them. Each of the vanes 10 is arranged in the circumferential direction with roughly equal intervals and makes a circular vane line. Additionally a channel 4 of working gas is formed only on a part at an outlet part of the impellers by providing a back side vane 1a and an abdomen side vane 1b and positioning these vane materials 1a, 1b by a stay 6.
