Abstract: A classification device enables more appropriate classification of users from various standpoints. A classification device is provided with an answer acquisition unit, a biological information acquisition unit, a determination unit, and a classification unit. The answer acquisition unit acquires, from a subject person, an answer to a prescribed question posed to the subject person. The biological information acquisition unit acquires biological information of the subject person. The determination unit determines the state of the subject person on the basis of the biological information acquired by the biological information acquisition unit. The classification unit classifies the subject person on the basis of the answer acquired by the answer acquisition unit and the state of the subject person determined by the determination unit.
