PROBLEM TO BE SOLVED: To provide a base isolation device having vibration control characteristics being equal to those of a conventional base isolation device or more without giving load to the environment. SOLUTION: A laminated body 16 is formed by arranging a plurality of elastically deformable rubber plates 18 and a plurality of metallic plates 20 for maintaining rigidity alternately. A metallic plate spring 22 having a curved part 22A formed by curving in a U-shape in a central part and arm parts 22B formed linearly in both end parts is arranged at a radial position using the laminated body 16 as the center on an outer peripheral side of the laminated body 16.
