An object of the present invention is to provide a bird damage preventing device that can suppress unintentional current flowing between electrical shock wires for a long period after it is installed, to thereby maintain its performance. Provided is a bird damage preventing device 1 including a base 4 that is formed of a nonconducting material and extends in a longitudinal direction, and a plurality of electrical shock wires 5, each of which is formed of a conducting material, embedded in the base 4 to have its upper part exposed outside, extends in the longitudinal direction, and has a curved outline without an angular portion in a cross section orthogonal to the longitudinal direction, to thereby not make it hard for the electricity to be easily discharged between the electrical shock wires 5.本發明是提供一種鳥害對策裝置，其在設置後可長時間抑制電擊部之間未預期的通電，而能夠維持性能。本發明之鳥害對策裝置(1)，包括：細長狀的基部(4)，由非導體形成；及複數電擊部(5)，係由導電體形成的硬質棒狀體，以一部分在上方露出的方式埋入該基部(4)，在該細長狀中的長邊方向延伸，與該長邊方向正交的剖面輪廓形狀為無角彎曲形狀；藉此在電擊部(5)之間不易發生放電。
