PROBLEM TO BE SOLVED: To provide a magnetic driving stirring apparatus which is driven and rotated by magnetic force transmitted from outside to stir a fluid in a vessel, wherein its stirring is carried out stably and efficiently over a long time. SOLUTION: The magnetic driving stirring apparatus 20 has a stirring blade 21, and a thrust ball bearing 22 for supporting the stirring blade 21 rotatably around a central axis 39, wherein the stirring blade 21 has an arm part 23a, 23b extending from the central axis 39 towards outside in the radial direction, a scooping slope part 24a, 24b extending inclinedly from a lower part of front edge in the rotary direction of each arm part 23a, 23b to backward, and a driven magnet 29a, 29b which is arranged at line symmetry around the central axis 39 and is responsive to rotation of an external driving magnet to rotate. In operating, a bearing mount 31 is held to be adhered to a wall side of the vessel by magnetic attraction force acting between the external driving magnet and the driven magnet.
