PROBLEM TO BE SOLVED: To provide a liquid-filled vibration isolator capable of improving vibration isolating performance while preventing generation of noise. SOLUTION: The vibration isolator is composed such that each opening (a center opening 24a, first to fifth inner side openings 24b1-24b5, and first to sixth outer side openings 24c1-24c6) has a respectively different opening area. Thereby, resonance frequencies of portions corresponding to the openings 24a-24c6 can be respectively dispersed, and concentration to a specific resonance frequency can be suppressed even if elastic partition films are composed with a uniform thickness, and dynamic characteristics (the vibration isolating performance) can be improved.
