To provide a building having a slab structure which controls the shearing deformation of a building in a horizontal plane through a slab structure excellent in shearing rigidity and shearing yield strength, and has excellent resisting force against horizontal power.

Panels 1 composed of plural sheets of cement hardened bodies are arranged. Each panel 1 is fixed to a stab support member 2 using a stopping tool to restrict a horizontal movement, and the whole or a part of mutual joints 11 of adjacent panels 1 is provided with restraint members 4 to control the horizontal slippage of the panel 1 caused by a horizontal shearing force acting on a slab.
