The present invention provides a mixing impeller and the like capable of properly performing mixing. A mixing impeller includes multiple blade pairs each having two blades, wherein the blades included in the multiple blade pairs are attached around a rotational shaft extending in a lateral direction, so as to be positioned at a same position in an axial direction of the rotational shaft, the two blades of each blade pair each have a shape that is symmetric about a symmetry plane that is a plane perpendicular to the rotational shaft, the two blades of each blade pair are formed so as to extend from the rotational shaft side toward an outer circumferential side, which is a side opposite to the rotational shaft side, and blade outer portions that are on the outer circumferential side are bent toward a side on which the two blades face each other.
