A metal filling process is provided in which micro holes formed in a work piece are filled with metal by immersing the work piece in molten metal and then removing the work piece from the molten metal. As the work piece is dipped into molten metal, a bottom surface of the work piece is tilted to an angle of 0.5° or more relative to the surface of the molten metal, and as the work piece is removed from the molten metal, a top surface of the work piece is tilted to an angle of 0.5° or more and less than 85° relative to the surface of the molten metal. Failures such as a work piece fracturing when it is dipped into molten metal, or when it is removed from molten metal, are prevented, and failures such as metal remaining on a surface of a work piece after the work piece has been removed from molten metal are also prevented.
