PROBLEM TO BE SOLVED: To solve the problem that a conventional metal net fence for preventing the invasion of a harmful animal can not protect an agricultural land from the invasion of such an animal, especially a deer which has a good jumping ability and can jump into the agricultural land over the fence. SOLUTION: On the upper part of supports of a metal net fence, bar-shaped bodies 3 are attached in such a manner that they protrude in the diagonal direction having an angle from the perpendicular direction of the fence. Two rows of wires 5 are placed on the tops and the middle positions of the bar- shaped bodies 3, respectively. This prevents a deer from jumping over the fence. When aluminum sheet straps 7 shinning by receiving light are hung on the wires, the cowardly deer, has an over powered feeling and hesitates approaching the fence.
