To provide organic resin coated steel of which a life can be prolonged further as compared with steel manufactured by a conventional technology.
The organic resin coated steel includes an iron phosphate chemical conversion treatment layer, an aluminum phosphate chemical conversion treatment layer, and an organic resin layer laminated on a surface of the steel in this order from a steel side. An average thickness of the iron phosphate chemical conversion treatment layer is 0.1-1 μm. The aluminum phosphate chemical conversion treatment layer contains metal M selected from P, Al, B, and Mg or Ca. A composition of the aluminum phosphate chemical conversion treatment layer includes a binder giving Al2O3/P2O5=0.2-0.6, B2O3/P2O5=0.01-0.1, MO/P2O5=0.01-0.2 at a molar ratio in terms of anhydrous oxide, and inorganic extender pigment.
