PROBLEM TO BE SOLVED: To provide a high strength wire netting formed with wire having a high tensile strength and having unevenness followability for an inclined surface, and a debris fall prevention net using that netting.SOLUTION: A high strength wire netting formed with a wire having a tensile strength in excess of 2200 MPa and having a deflection amount of 707 mm or more as a net body under the following conditions. Conditions: The net body is supported in the line direction in a cantilever state with a cantilever length of 1000 mm, and the displacement amount in the vertical direction of the free end is taken as the deflection amount.SELECTED DRAWING: Figure 1 【課題】引張強さが高いワイヤーによって形成しつつも、斜面の凹凸への追従性を有する高強度金網及びこれを用いた落石予防網の提供。【解決手段】２２００ＭＰａを超える引張強さを有するワイヤーによって形成され、下記条件による網体としてのたわみ量を７０７ｍｍ以上であることを特徴とする高強度金網。条件：網体を列線方向に片持ち梁状に支持して片持ち梁の長さを１０００ｍｍとし、この際の自由端の鉛直方向の変位量をたわみ量とする。【選択図】図１
