PROBLEM TO BE SOLVED: To provide a composite material with MgB<SB>2</SB>particles, which is excellent on superconductive characteristics and uses magnesium or magnesium alloy for a base phase. SOLUTION: The MgB<SB>2</SB>particles are filled up in a cavity of a mold, the magnesium or the magnesium alloy at a molten or half-molten state is infiltrated into the MgB<SB>2</SB>particles in the cavity of the mold at a pressurized state from one side, and the mold is simultaneously cooled from the other side in order to manufacture the magnesium composite material. It is preferable that an average particle size of the MgB<SB>2</SB>particles is 50μm or below. Furthermore, the MgB<SB>2</SB>particles may be filled up in the cavity of the mold at pressure of 0.05-10 MPa, or a preformed body of the MgB<SB>2</SB>particles molded in advance at pressure of 0.05-10 MPa may be used.
