In a method of manufacturing a Ni plated coating that includes at least one Ni plated layer, an agitation intensity of a plating bath is changed while the Ni plated layer is being electrodeposited to change potential of the deposited Ni plated layer in a deposition depth direction. A Ni plated coating including a D-Ni plated layer and a B-Ni plated layer adjoining the D-Ni plated layer has, other than an interface voltage changing region at an interface between the D-Ni plated layer and the B-Ni plated layer, an in-layer voltage changing region in which, in the D-Ni plated layer or in the B-Ni plated layer, potential is changed in a deposition depth direction at an average rate of 1 mV/0.1 m or greater.

A steel sheet for cans has, on the surface thereof, in order from the steel sheet side, a chromium metal layer and a hydrous chromium oxide layer. The chromium metal layer is deposited in an amount of 65-200 mg/m.sup.2, and the hydrous chromium oxide layer is deposited in an amount of 3-15 mg/m.sup.2 in terms of chromium. The chromium metal layer includes: a flat chromium metal layer that has a thickness of at least 7 nm; and a granular chromium metal layer that includes granular protrusions that are formed on the surface of the flat chromium metal layer. The maximum grain size of the granular protrusions is 100 nm or smaller. The number density of the granular protrusions per unit area is 10/m.sup.2 or higher.
