Abstract
A viscosity estimation device includes: a current detector detecting a drive current supplied to an induction motor which stirs a substance due to rotation of a rotating shaft which is rotationally driven; a rotation detector detecting rotation of the rotating shaft; and a calculator obtaining a viscosity correlation value, which is a value having a correlation with a viscosity of the substance, using a detection result of the current detector and a detection result of the rotation detector.
