An agitation apparatus and an agitation method that ensure rapid and homogeneous agitation/mixing of fluids with a wide spectrum of viscosities from low to high levels and fluids with high thixotropy throughout an agitation vessel are provided. In an agitation apparatus, a lowest upper agitation blade is arranged to be vertically adjacent to a lower blade. As viewed from above, a line on a plane connecting a lower end portion of the lowest upper agitation blade to the center of an agitation shaft is arranged by a predetermined angle with respect to the center line of the lower blade in a blade radial direction. As viewed from the side, a horizontal cross section including the lower end portion of the lowest upper agitation blade is located below a horizontal cross section including an upper end portion of the lower blade.
