PROBLEM TO BE SOLVED: To evade deterioration in sealing properties with the lapse of time, and to improve physical properties such as mechanical properties and electrical properties in a sprayed coating-coated member. SOLUTION: In the sprayed coating-coated member, the surface of a metal base material is provided with a sprayed coating subjected to sealing treatment with a sealing treatment agent, and the surface layer of the sprayed coating before the sealing treatment is removed by a prescribed thickness before the sealing treatment. The sealing treatment agent comprises epoxy group-containing components and a curing agent, and does not comprise a polymerizable vinyl group-containing solvent. The epoxy group-containing components are a mixture using a polyglycidyl ether compound in which the number of epoxy groups included in one molecule is three or more as an essential component, and comprising at least one selected from an alkylene diglycidyl ether compound and a ring aliphatic diepoxy compound in which the number of epoxy groups included in one molecule is two, and, the polyglycidyl ether compound is blended by 10 to 80 wt.% based on the whole of the epoxy group-containing components other than the curing agent.
