To provide a fence structure and a fence body installed according to the inclination of an inclined installation face and having sufficient strength.

The fence structure includes posts 2 and the fence body 3 mounted to the posts 2 through connection parts 4. The fence body 3 includes horizontal rails 6 and vertical bars 7 connected to the horizontal rails 6 so that the axial direction intersects the axial direction of the horizontal rails 6. The vertical bars 7 and the horizontal rails 6 are connected relatively turnably so that the intersecting angle of both axial directions changes. The fence body 3 is mounted to the posts 2 by connecting the vertical bars 7 to the posts 2 through the connection parts 4. The connection part 4 includes a fence projecting part 9 integrally formed at the vertical bar 7 to project from the side face of the vertical bar 7, and a post projecting part 5 integrally formed at the post 2 to project from the side face of the post 2. The connection part 4 is constituted by placing the fence projecting part 9 on the post projecting part 5.
