PROBLEM TO BE SOLVED: To prevent cracking in a side edge part, which becomes a problem when a breadth is expanded in the case of a thin base-material steel plate, in a clad steel plate formed by making the surface of the base-material steel plate undergo the padding of a abrasion-resistant metallic material by welding. SOLUTION: Many linear projections 4, 4, etc., are regularly installed on the surface of the base-material steel plate 1 in such a manner that each of the linear projections 4, 4, etc., is located approximately perpendicular to the four sides of the steel plate 1 and the adjacent two linear projections 4, 4, etc., are located approximately perpendicular to each other.
