An object is to provide a lubrication treatment method of a metal wire rod, in which not a combination of acid washing/alkaline degreasing and phosphate/soap treatment each causing a large burden on the environment, but shot blast and a coat-type treatment agent are used to allow for a significant reduction in burden on the environment, and a batch manner is applied to allow for practical production efficiency and uniformly form a lubrication coating on a metal wire rod. The object is achieved by a lubrication treatment method of a metal wire rod, which is a method for lubrication treatment of a coiled metal wire rod in a batch manner, including a descaling step of performing shot blast treatment of a coiled metal wire rod, and a lubrication coating formation step of applying a lubricant to the metal wire rod after the descaling step, in which the coiled metal wire rod satisfies L/(dN)1.1 in the descaling step under the assumption that the coil width is L, the wire diameter of the metal wire rod is d, and the number of coil turns is N, and the lubricant contains one or more coating base components (A) selected from the group consisting of an inorganic salt and an organic acid salt, and a lubrication component (B).
