PROBLEM TO BE SOLVED: To provide a sunlight-collecting film mirror which has high reflectance and excellent in weather resistance and scratch resistance; and a method for producing the same.SOLUTION: A sunlight-collecting film mirror has a surface coating layer 1 containing an ultraviolet ray shielding agent, a silver reflection layer 3, and corrosion prevention layers 2 and 4 adjacent to the silver reflection layer 3, on a resin base material 5. The surface coating layer 1 contains the ultraviolet ray shielding agent, and is cured by polymerization reaction using a photoinitiator having absorption maximum within the wavelength range of 380-460 nm.SELECTED DRAWING: Figure 1 【課題】反射率が高く耐候性及び耐擦傷性に優れた太陽光集光フィルムミラー及びその製造方法を提供する。【解決手段】太陽光集光フィルムミラーは、樹脂基材５上に、紫外線遮蔽剤を含有する表面被覆層１、銀反射層３及び当該銀反射層３に隣接した腐食防止層２、４を有し、表面被覆層１に紫外線遮蔽剤を含有させるとともに波長３８０〜４６０ｎｍの範囲内に吸収極大を持つ光開始剤を用いた重合反応により硬化された層とすることを特徴とする。【選択図】図１
