PURPOSE:To directly connect the corner parts of the bottom surface of the metal sidewall to the recessed inner wall of the metal frame by a method wherein a conductive plate with its one side part fitted on the outer periphery of the metal sidewall supporting body of the container with a diaphragm is prepared. CONSTITUTION:The recessed part of a conductive plate 13 is firmly fitted on the outer periphery of a metal sidewall supporting body 6 and the conductive plate 13 is connected to the supporting body 6. The contact parts of the conductive plate 13, which have respectively numerous notches at the edge ends on the opposite side to the recessed part, are catched on the inner part of a metal frame 1. The intermediate part of the conductive plate 13 is pressed by the corner parts of the bottom surface of the metal sidewall 5 of the container, whereby the conductive plate 13 is made to sag. By this way, the corner parts of the bottom surface of the metal sidewall are securely connected to the recessed inner wall of the metal frame in a short time. |
