A fence installed in a standing state for partitioning a predetermined place into an area on inside and an area on outside, the fence comprising:

• a plurality of posts;
• a pair of plate members extending between the plurality of posts in a horizontal direction and fixedly attached to the plurality of posts, the pair of plate members being spaced away from each other in a vertical direction;
• and
• a blocking member arranged in the space between the plate members for keeping a foot of a person from entering the space between the plate members to prevent the person from clambering over the fence, wherein
• a lower end of the blocking member is spaced upward from the plate member at a lower position, and defines a lower gap against an upper surface of the plate member at the lower position, the lower gap having such a dimension as to keep a tip of the foot of the person from entering the lower gap.
