A vibration control device is provided which enables an awakening effect for a user to be increased while making it difficult to give discomfort to the user. A harmonic signal generating section (2) of a vibration control device (1A) is configured to successively output a plurality of alternating signals for driving a vibration unit (20A), (20B). By means of the plurality of alternating signals which is successively output and has a frequency ratio represented with a predetermined integer ratio, vibration generated with the plurality of alternating signals can more easily awaken a user while making it difficult to give discomfort to the user.
