PROBLEM TO BE SOLVED: To provide a resin-coated seamless can excellent in corrosion resistance and impact resistance. SOLUTION: In the resin-coated seamless can 10 comprising a resin coated metal sheet 1 wherein a polyester resin layer 3 containing polyethylene terephthalate is applied to the surface of a metal substrate 2, the infrared two- color ratio (R1) of the polyester resin layer on the inner surface of a can body part represented by the formula, R1=Iw(⊥)/Iw(||) (wherein, Iw(⊥) is the absorption intensity of infrared rays of 973 cm<-1> to polarizing infrared rays vertical to the can height direction of the can body part and Iw(||) is the absorption intensity of infrared rays of 973 cm to polarizing infrared rays parallel to the can height direction of the can body part) is set to 1.1 or more. |
