A steel sheet for a fuel tank includes: a Zn-Ni alloy plated layer which is placed on one surface or each of both surfaces of a base metal and formed on at least one surface; and an inorganic chromate-free chemical conversion coating film which is placed over the Zn-Ni alloy plated layer. The Zn-Ni alloy plated layer has a crack starting from an interface between the Zn-Ni alloy plated layer and the inorganic chromate-free chemical conversion coating film and reaching an interface between the Zn-Ni alloy plated layer and the steel sheet, and a water contact angle on a surface of the inorganic chromate-free chemical conversion coating film is more than or equal to 50 degrees.
