PROBLEM TO BE SOLVED: To provide a stirring blade for slurries which has no residence of slurries in the central part of a stirring tank, a little driving power and also can be produced with low cost due to a simple structure in a stirring apparatus having an aim of a slurry suspension in stirring of slurries of the concentration of 20-50%. SOLUTION: An upper-step side stirring blade 2 which is formed by arranging two sheets of inclined blade 2a, 2a axisymmetrically to the rotation center, and a lower-step side stirring blade 3 which is formed by arranging an inclined blade 3a, 3a shorter than the inclined blade 2a axisymmetrically to the rotation center, are positioned closely in the upper and lower sides to form the stirring blade 1 for slurries.
