It is an object of the present invention to provide a contents reproducing device which can perform an intermittent operation with improved responsiveness to user request. The contents reproducing device according to the present invention includes: an input operation unit (1100), a system state managing unit (1210), a system information storing unit (1220), a contents reproduction control unit (A) (1230), a state after next candidate extracting unit (1240), a contents reproduction control determining unit (1250), and a contents reproducing unit (1300). The contents reproduction control determining unit (1250) determines whether or not a candidate related to the contents reproduction control is in the state after next candidates extracted by the state after next candidate extracting unit (1240). Therefore, the contents reproducing device according to the present invention can improve responsiveness to the user request by shortening the cycle of the intermittent operation of the contents reproducing unit (1300) when it is determined that there is a possibility that a user request related to the contents reproduction control is inputted, and by lengthening the cycle of the intermittent operation of the contents reproducing unit (1300) when it is determined that there is no possibility that a user request related to the contents reproduction control is inputted.
