PURPOSE:To mold a inner metal cover with a conductive resin to enhance high electromagnetic wave shield effect. CONSTITUTION:An inner metal cover 1 is divided up and down and the fitting part is in contact with each other by metals. In order to prevent loosening between an outer metal cover 1 and the cover 4, they are connected with a partial hole 1a and a projection 4a. A lead wire 8 of a coaxial cable 6 is connected to a plug 7, and the cover 4 divided up and down is set with a conductive resin mold 3 which is insert-molded and inserted into a specified mold, then an outer mold 2 is molded. An integrated support 3a is formed in the cover 4 to prevent deformation of the cover 4 caused by pressure in molding. The hole 1a and the projection 4a are arranged in the whole circumference of the connection part to strengthen the connection of the covers 1, 4. Contact between metals in the fitting part of the cover 4 is strengthened, conductive area is widened, and electromagnetic wave shield effect can be enhanced.
