A silver plating material having excellent wear resistance is provided. SOLUTION: In a silver plating material in which a silver plating film having a thickness of 10 μm or less is formed on a material made of copper or a copper alloy, the arithmetic average roughness Ra of the surface of the silver plating film is 0.1 μm or less, The {111} orientation ratio of the silver plating film is 35% or more. This silver-plated material is a silver-plated material in which the wear amount of the silver-plated film (the thickness of the worn silver-plated film) is less than 1 μm even when the silver rivet is slid 300,000 times with a load of 100 gf, that is, the silver-plated film Is a silver-plated material in which the base material is not exposed after the silver rivet is slid 300,000 times with a load of 100 gf even when the thickness is about 1 μm, and has extremely excellent wear resistance.
