PCT No. PCT/JP96/01368 Sec. 371 Date Dec. 1, 1997 Sec. 102(e) Date Dec. 1, 1997 PCT Filed May 23, 1996 PCT Pub. No. WO96/38600 PCT Pub. Date Dec. 5, 1996Adhesion of nickel plated steel sheets with each other, which is apt to occur during producing a steel sheet in which nickel is diffused by heat treatment of a nickel plated steel sheet in an annealing furnace, is prevented. A nickel plated steel sheet having a nickel-iron diffusion layer of 0.5-10 mu m thickness, a nickel plated layer thereon of 0.5-10 mu m thickness, and a silicon oxide layer thereon as an amount of silicon of 0.1-2.5 mg/m2 are formed on at least one face of a cold rolled steel plate. After the nickel is plated on the cold rolled steel plate, silicon hydrate is precipitated by dipping or electrolysis treatment in a bath of sodium orthosilicate as a main component, followed by heat treatment.
