PROBLEM TO BE SOLVED: To provide a low-cost planar combined member obtained by stacking an Al based sheet material and iron based sheet materials and joining and integrating them, which has high productivity, has reliability as well, and is suitable for a brake rotor. SOLUTION: In two sheet stocks 2A, 2B of iron base materials for surface materials, thorough holes 3A, 3B passing from either sheet face to the other sheet face are previously formed. The two sheet stocks for surface materials are stacked on both the surfaces of a sheet stock 1 of an Al material for a core material, so as to be a stacked body 4. The stacked body is compressed from both the sides. By the compressive force, the material of the sheet stock for a core material is plastically made to flow so as to be infiltrated into the through holes. Also, the compression is performed in such a manner, even after the material of the sheet stock for a core material is filled into the through holes, the compression further progresses, and the sheet stock for a core material and the sheet stocks for surface materials are joined.
