A metallic plate material used as a material for, for example, a casing for
containing parts of an electric/electronic instrument, which is good in
earthing properties, shield properties against electromagnetic waves,
formabilities, lubricity, sliding properties, and resistance to solvents.
The metallic plate material comprises a resin-coated metallic plate
material. The resin coating contains, as resin, at least one substance
chosen from a group consisting of acrylic-based resin, epoxy-based resin,
and urethane-based resin, and contains water in the amount of 1 to 50 mass
% and a lubricant in the amount of 0.1 to 20 mass %, and has a thickness
of 0.05 to 5 .mu.m.
