An agitating blade (100), which agitates a fluid by rotation, is provided with axially projecting vanes (110, 120) disposed on at least one surface, and recesses (102) circumferentially adjacent to the vanes (110, 120). The agitating blade has a plurality of projections (111, 121, 122) which impact the fluid, the projections being arranged on a leading edge side in the rotation direction of the vanes (110, 120) and radially spaced apart from one another. |
