PROBLEM TO BE SOLVED: To provide an anti-vibration bushing of a bonded type comprising an outer cylinder and an inner cylinder of hard material, a rubber elastic body disposed between them to connect them to each other, and an intermediate plate embedded in the rubber elastic body to harden spring characteristics, in which the number of parts for necessary hard parts is reduced, and which can be easily and automatically manufactured by an automatic machine. SOLUTION: This anti-vibration bushing 10 comprises the outer cylinder and the inner cylinder 14 of hard material, the rubber elastic body 16 disposed between them, and the intermediate plate 18 of hard material, curved in curvature along an inner circumferential surface of the outer cylinder 12 and an outer circumferential surface of the inner cylinder 14, and embedded in the rubber elastic body 16. The intermediate plate 18 is formed as an integrated ring continuous along the whole circumference. A pair of opening window parts 20 are provided in the intermediate plate 18 to face each other perpendicularly to an axial direction to penetrate thickness of the intermediate plate 18.
