A viscous liquid stirring device comprising a first rotary shaft and a second rotary shaft which are arranged in parallel to each other in the horizontal plane in the vessel. The rotary shafts have a plurality of rotors thereon and are rotated at the same speed and in the same direction that the upper face of the first rotary shaft moves away from the second rotary shaft.
