PROBLEM TO BE SOLVED: To provide a diffuser panel capable of restricting a pressure loss at a discharging flow passage from becoming too high while restricting reduction in diffusibility of discharging gas at the discharging flow passage.SOLUTION: This invention relates to a method for manufacturing a diffuser panel having a shape in which a plurality of blades are protruded out of a cylinder member comprising the steps of correcting for applying a correcting work against one developed metallic plate formed with a band part having an arc-curved shape in one plane and a plurality of blades at one side in a width direction of the band part and protruded out of the one side corresponding to an outside of the arc-curved shape in such a way that the shape of the band part becomes a straight line shape as compared with the arc-curved shape, and after the correcting step, forming the band part into a cylindrical shape to form the cylinder member. |
