The present invention provides an emotion estimation device that can improve convenience of obtaining biological information when estimating emotions, and estimate emotions with high accuracy. The emotion estimation device (1) of the present invention includes a control unit 20. The control unit 20 has an emotion estimation model 30 for estimating an emotion based on biological information Bi, and is configured to estimate the emotion of a person to be estimated U based on the biological information Bi of the person to be estimated U. The emotion estimation model 30 includes an nth degree biological information distillation model made by using n-1th degree knowledge information. The control device 20 uses the nth degree biological information distillation model to estimate the emotion of the person to be estimated U based on the biological information Bi of the person to be estimated U which is included in the types of biological information Bi required for estimating emotion by using a first degree model 100
