Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a reflector for an LED light emitting device having excellent reflectance.SOLUTION: The reflector for an LED light emitting element includes a silver plating layer on a base material made of a copper alloy. A surface of the silver plating layer has a thickness of 0.1 to 1.0 μm, preferably has an arithmetic average roughness Ra in a range of 0.25 to 0.55 μm.SELECTED DRAWING: None 【課題】優れた反射率を備えるＬＥＤ発光素子用反射板を提供する。【解決手段】ＬＥＤ発光素子用反射板は、銅合金からなる基材上に銀めっき層を備え、該銀めっき層の表面は、０．１〜１．０μｍ、好ましくは０．２５〜０．５５μｍの範囲の算術平均粗さＲａを備える。【選択図】なし
