PROBLEM TO BE SOLVED: To surely shield electromagnetic wave by a steel driving mold. SOLUTION: A metal plate 5 with electromagnetic wave shield function is provided at a connection part between steel driving molds used as a beam mold 1 and a floor mold 2. Through the metal plate 5, the beam mold 1 and floor mold 2 are connected electrically to each other, and a space between these molds is closed. The metal plate 5 is pre-installed on either of the beam mold 1 and floor mold 2 in the state of being closely fitted with each other, and overlapped closely on the other mold to connect them with each other. Using a steel folded plate driving mold as the beam mold 1, the metal plate 5 is installed on a steel runner hardware 3 on the upper part of the driving mold, and the edge part of the floor mold 2 is supported on the upper part of the beam mold 1 in the state of being fitted to the metal plate 5. Then, the metal plate 5 is bent, and overlapped on the floor mold 2.
