PROBLEM TO BE SOLVED: To provide a base isolation device capable of minimizing an installation space and maintaining the initial damping functions over a long time without deterioration with long-term use. SOLUTION: This base isolation device 1 is provided with a shoe 3, a shoe 5 disposed movably relatively on the shoe 3, a base isolation mechanism 8 provided between the shoes 3, 5 so as to isolate the relative vibration of the shoe 5 in the horizontal direction based on the horizontal vibration of the shoe 3, and a damping mechanism 9 recovering the relative position in the horizontal direction between the shoes 3, 5.
