Abstract
A forming sheet for forming an article such as a housing for an electronic device having a shieldability against electromagnetic interference. It is made by laminating a conductive laminated sheet to a thermoplastic synthetic resin sheet through a hot melt adhesive layer. The conductive laminated sheet is formed by subjecting to heat shrinkage a substrate comprising a metallic film and a heat-shrinkable synthetic resin film laminated together through a discontinuous bonding layer. The conductive layer is less liable to crack due to stress applied during forming.
