PURPOSE: A clad steel plate which has superior bonding force between dissimilar metals made of corrosion resisting material and carbon steel and is inexpensive, and a method for manufacturing the clad steel plate are provided. CONSTITUTION: The method for manufacturing a corrosion resistance clad steel plate comprises the processes of tack welding a thin strip(2) of amorphous alloy having a principal constituent of Fe as a first binder(2) onto one surface of both surfaces of a carbon steel plate; and bonding the materials by resistance core welding a corrosion resistance metal plate(4) to the tack welded part after putting a corrosion resistance metal plate on the tack welded part, wherein a thin strip(3) having a principal constituent of Ni as a second binder is tack welded onto the thin strip(2) of amorphous alloy having a principal constituent of Fe as a first binder(2), the second binder is a thin strip of stainless steel-copper alloy, the corrosion resistance metal plate(4) is titanium, zirconium, tantalum, niobium, nickel, copper and alloy thereof, a flux is coated on the first binder and the second binder, and a plurality of the first and second binders are alternately stacked. In a clad steel plate in which a corrosion resistance metal plate(4) is bonded onto one surface of both surfaces of a carbon steel plate, the clad steel plate is characterized in that a thin strip(2) of amorphous alloy having a principal constituent of Fe as a first binder is welded between the carbon steel plate and the corrosion resistance metal plate(4).
