　Provided is an emotion estimation device whereby it is possible to suppress a decrease in precision of identifying an emotion due to fluctuation in an emotion estimation reference. The emotion estimation device according to an embodiment of the present invention is provided with: a classification means for classifying, on the basis of a second emotion, a biological information pattern variation amount indicating a difference between biological information measured by a sensing means from a test subject in a state in which a stimulus for inducing a first emotion is applied, the first emotion being one of two emotions obtained from a plurality of combinations of two different emotions from among a plurality of emotions, and the biological information measured in a state in which a stimulus for inducing a second emotion which is the other of the two emotions is applied after the previous biological information is measured; and a learning means for learning a relationship between the biological information pattern variation amount and each of the plurality of emotions as the second emotion for which the biological information pattern variation amount was obtained, on the basis of the result of classification of the biological information pattern variation amount.
