Abstract
Provided is a clad steel plate with excellent thermal conductivity that can be used suitably in cookware and the like. The present invention is a three-layer clad steel plate having a carbon steel base material and stainless steel mating material disposed respectively on both surface sides of the base material, wherein a plate thickness ratio L given by Equation (1) is 1.0-5.0 and at least one surface of the clad steel plate has a plurality of protrusions and recesses. Plate thickness ratio L=the plate thickness of the base material/the total thickness of the mating material . . . Equation (1) Here, the base material thickness and the mating material thickness are the thicknesses at the protrusions.
