PURPOSE:To obtain a laminated steel sheet having improved adhesion between the base material and Ti by placing metal frame on the surface of a steel sheet to be adhered, spreading Ti powder in the frame and carrying out sintering by hot pressing in an inert gaseous atmosphere. CONSTITUTION:The surface of a steel sheet 3 to be adhered is cleaned and a metal frame 2 is placed on the cleaned surface. Ti powder is spread in the frame 2 to a prescribed thickness and sintering is carried out by hot pressing under >=586kgf/cm<2> pressure in an inert gaseous atmosphere. Iron powder 4 and Ti powder 1 may by successively spread in the frame 2 in layers in place of the Ti powder 1. The resulting Ti laminated steel sheet has such superior characteristics as superior bendability, shearing strength and resistance to stripping or Ti.
