To strengthen adhesion between a plate member and a rubber elastic member and to improve the durability of the rubber elastic member.

A rubber vibration isolator comprises two plate members 1, 2 and a rubber elastic member 3 which is arranged so as to connect the plate member 1 with the plate member 2. Adhesive parts 4, 5 of thin layer are interposed between the plate member 1, 2 and the rubber elasticity member 3, thereby to stick the plate members 1, 2 to the rubber elasticity member 3 adhesively. The adhesive parts 4, 5 are formed so as to ring beyond the opposing face of a part between the plate member 1 and the rubber elasticity member 3 and a part between the plate member 2 and the rubber elasticity member 3, respectively.
