  However, in the above-described conventional example, the work of attaching the bearing plate and the panel to the panel is necessary, and there is a possibility that the construction efficiency is lowered and the cost is increased.

  The present invention has been made in view of the above points, and an object of the present invention is to provide an earthquake-resistant structure capable of forming a bearing wall by preventing reduction in construction efficiency and cost. .

The earthquake resistant structure according to claim 1 of the present invention is an earthquake resistant structure formed by attaching a panel 4 formed by filling a heat insulating material 3 between two metal jackets 1 and 2 to a wall base material 9. The panel 4 is connected to the wall base material 9 via a connector 5 at the metal sheath 2 on the wall base material 9 side, and the panel 4 and the wall base material 9 are connected by the connector 5. The position is at least a diagonal position of the panel 4, and the number of the coupling tools 5 per unit area at each of the diagonal positions is larger than the other positions of the panel 4.
