PROBLEM TO BE SOLVED: To provide a vibration control device which efficiently exerts vibration control performance to a certain amplitude vibration periodic-band, enables cost-reduction and shortening of a construction term in forming liquid-storage spaces, and facilitates pouring of liquid in the storage spaces without making an error in the quantity of the liquid to be poured. SOLUTION: The vibration control device includes a liquid tank 3 which is installed in a structure. Vibrations of the construction are suppressed by the fluid dynamic force generated by sloshing of the liquid L stored in the tank 3. The liquid tank 3 includes a plurality of liquid-storing spaces 6A-6C whose dimensions W<SB>1</SB>-W<SB>3</SB>in the vibration direction X of the structure are made different from each other.
