Provided is a coating composite material and a movable contact part for a movable contact part, which has excellent adhesion to plating with respect to repeated shear stress, has a stable contact resistance value for a long period of time and is improved in life of the switch. A base layer made of any one of nickel, cobalt, nickel alloy and cobalt alloy is formed on at least a part of the surface of the stainless steel base material, an intermediate layer made of copper or a copper alloy is formed on the base layer and a silver or silver alloy layer Wherein the intermediate layer has a thickness of 0.05 to 0.3 占 퐉 and the average grain diameter of silver or silver alloy formed on the outermost layer is 0.5 to 5 占 퐉. |
