PURPOSE:To continue electromagnetic shielding effect for a long period of time and to improve mechanical strength by laying an electromagnetic shield on a lower mold, supplying melted synthetic resin, then inserting moldings in which upper and lower molds are engaged to another lower mold, supplying melted synthetic resin, and then engaging upper and lower molds. CONSTITUTION:An electromagnetic shield 7 is laid on a lower mold 13, and conductive metal member such as copper, iron, stainless steel, such as mesh metal, punching metal, etc., is desirably used as the shield 7. Melted synthetic resin 10 is supplied into the mold 13. Here, general synthetic resin such as polyethylene, polypropylene, etc., is desirably used as the resin 10. Then, an upper mold 12 is driven to engage the upper and lower molds 12, 13, and the shield 7 is shaped in a state filled in the resin. Thus, the shield is uniformly filled in a housing in small number of working steps. |
