Abstract
A conductive cover has at least two cases connected to each at their connecting surfaces. The cases are provided with electrical continuity through a conductive electrodeposition coating layer at the connecting surfaces. The conductive cover is excellent in electromagnetic shielding properties and also suitable for an exterior cover.
