A stirring state detecting method of the present invention is a method for detecting a stirring state of a test solution by using: a sample cell (101) which holds the test solution in an internal space thereof; a stirring device (111) which stirs the test solution held in the sample cell (101); a light emitting device (106) which emits light to the test solution held in the sample cell (101); and a photoreceiver (108) which receives the light, and includes the steps of: (A) in a state in which the test solution is held in the sample cell (100), activating the stirring device (111) to change a liquid level (102) of the test solution by stirring; (B) emitting the light from the light emitting device (106) to the test solution held in the sample cell (100); (C) detecting by the photoreceiver (108) an amount of the light which is emitted to the test solution and subjected to an action of the test solution whose liquid level (102) is changed by the stirring; and (D) determining the stirring state of the test solution based on the amount of the light detected by the photoreceiver (108) in the step (C).
