A response style component removal device capable of removing a RS that does not depend on content of a questionnaire is provided. The response style component removal device includes a parameter learning unit that uses, as learning data, rating values for a plurality of question items from a plurality of raters who have rated all of K types of questionnaires (K is an integer equal to or greater than 2), each of the K types of questionnaires including the plurality of question items, to learn a rater parameter θk that depends on at least an index k (k=1, . . . , K) of each questionnaire and indicates a tendency of each rater, an item parameter βk that depends on at least the index k (k=1, . . . , K) of each questionnaire and indicates a tendency of each question item, and a response style parameter γ that does not depend on at least the type of each questionnaire and indicates a tendency of a response style, the rater parameter θk, the item parameter βk, and the response style parameter γ being parameters describing the rating values, and a response style component-removed probability distribution generation unit configured to remove, among the rater parameter θk, the item parameter βk, and the response style parameter γ that have been learned, the response style parameter γ to generate a probability distribution of the rating value.
