A content search device includes an identification section (371) and a recommended list generation section (372). Among a plurality of favorite content lists D_t defined so as to correspond to a plurality of users (u) and indicating a favorite content of each user (u), the identification section (371) specifies a favorite content list of another user (u) indicating the same content as the content indicated by the favorite content list D_t1 of a user u_A. By using the favorite content list D_t1 and the favorite content list D_t of the other user (u), the recommended list generation section (372) performs ranking according to the number of contents indicated by the favorite content list D_t of the other user and generates a recommended content list D_rl.
