An automobile fuel container material and container has good workability, corrosion resistance of internal and external surfaces and weldability. Excellent environmental adaptability arises from the material being free from the elution of harmful components such as lead and chromium(VI). The automobile fuel container material includes a steel sheet, 5 to 80 g/mzinc plating as a first layer on at least one side of the surface of the steel sheet, 10 g/mnickel plating as a second layer, and not more than 5 g/mof a post-treatment layer. The post-treatment layer forms by coating partially reduced chromic acid and a reducing organic compound or can be an electrolytic chromate film as a lower layer and a resin as an upper layer.
