Claim 5:
6. A stirring device comprising:
a rod-shaped body configured to form a cylindrical shape and configured to have a magnetic force at a first end portion and to have a magnet force at a second end portion opposite to the first end portion in a longitudinal axis;
a liquid container configured to include the rod-shaped body placed therein and to contain liquid; and
a rotating body configured to face a bottom of the liquid container from below, to rotate on a rotation shaft, and to include magnets at a plurality of positions,
wherein a first blade and a second blade extend from each of the first end portion and the second end portion of the rod-shaped body in the longitudinal axis, respectively,
wherein the first blade and the second blade each have a plate shape and,
on an orthogonal plane orthogonal to the longitudinal axis, the plate shape has a cross sectional area less than the cross sectional area of the first end portion or the second end portion, and
wherein the rod-shaped body includes a preventing portion configured to prevent rotation in a circumferential direction of the rod-shaped body about the longitudinal axis of the rod-shaped body, and in the orthogonal plane, the preventing portion extends to both sides of the longitudinal axis with a length greater than a radius of the rod-shaped body.
