PURPOSE:To obtain a combined body having good combination and high strength by laying a fibrous forming body for reinforcement on the pressurized sintered body consisting of soluble salt, pouring and pressed molten light alloy to make a permeation body and pouring a metal under high pressure after dissolving the salt out. CONSTITUTION:The pressurized sintered body 2 consisting of the soluble salt, such as sodium chloride, potassium chloride, etc., is laid in the mold 1 and the fibrous forming body 3 for reinforcement, such as ceramic, etc., is laid on the above-mentioned body 2. On the above, the molten Al alloy or Mg alloy is poured and pressed 5 to permeate into the fibrous forming body 3. The pressurized sintered body 2 is dissolved and removed by water, etc., to make the surface to the coarse face having irregularity. The coarse face of the permeating fibrous forming body 6 is positioned at the upper part and charged into the mold 8 and the molten metal 9 is poured under high pressure. As the both is combined firmly by the coarse face having the irregularity, the combined by with the fiber reinforced complex and the metal, for example, for the 'Piston(R)', etc., is produced under good combination and high strength.
