To provide an ethylenic resin for steel coating having improved thermal deformation resistance without excessively lowering impact strength which linear low-density polyethylene has.

The ethylenic resin for steel coating satisfies all of the following conditions: (a) a density of 890-930 kg/m3; (b) a melt flow rate (MFR) of 0.1-10 g/10 min; (c) an energy of activation for fluidity (Ea) of <50 kJ/mol; (d) Mz/Mw ≥3.5; (e) (Mz/Mw)/(Mw/Mn)≥0.9; and (f) a quantitative proportion of eluted resin at ≥100°C, measured by temperature rising elution fractionation, of <1 wt.% (provided that the weight of the ethylenic resin is considered to be 100 wt.%).
