The can body member includes a cylindrical first steel sheet, Ni plating that is formed on an inner circumferential surface of the first steel sheet, a polyester film that is formed so as to be disposed on the outermost surface of the inner circumference of the can body member, and a chromate film that is formed between the first steel sheet and the polyester film. The amount ofNi plating is 10 to 1000 mg/m 2 , the amount of chromate film is 2 to 30 mg/m 2 expressed in terms of Cr metal, and the amount of metal plating which is closest to the outermost surface of the inner circumference of the can body member is 200 to 4000 mg/m 2 . The can bottom member includes a second steel sheet, and Sn plating that is formed on the can body member side of the can bottom member. The Sn plating is on or above the second steel sheet, and the Sn plating includes Sn single metal plating in the amount of 2 to 20 g/m 2 . |
