A content usage device includes (i) a license management unit that holds license information and (ii) a content output unit that uses a content in compliance with license information and outputs the content in at least one manner of a sound, video and data. The license management unit, upon receiving a request of license information from the content output unit, requests a license management unit of another content usage device to transfer the license information and acquires the license information, and passes the acquired license information to the content output unit. The content output unit uses a content in compliance with the license information passed from the license management unit.
