Surface-treated metal sheet, coated member, and method for producing coated member
Provided are a surface-treated metal sheet excellent in the adhesiveness to a coating treatment film and weldability and a coated member. The surface-treated metal sheet includes a metal sheet and a coating film placed on at least one major surface of the metal sheet; the coating film contains oxide particles, a binder resin, and electrically conductive particles; the amount of electrically conductive particles contained is 5 to 30 mass % relative to the coating film; the oxide particles include non-doped oxide particles and/or doped oxide particles; the non-doped oxide particles include at least one kind selected from the group consisting of zinc oxide particles, tin oxide particles, magnesium oxide particles, calcium oxide particles, and strontium oxide particles; the doped oxide particles include at least one kind selected from the group consisting of doped zinc oxide particles and doped tin oxide particles; the amount of oxide particles contained is 1 to 30 mass %, but is 1 to 10 mass % relative to the coating film in the case of not including doped oxide particles; and the amount of the coating film attached to the major surface is 2 to 20 g/m2.
