Abstract
Disclosed is a gasket having electric and adhesive properties as well as electromagnetic wave shielding functions and a method for manufacturing the same. The gasket includes an adhesive polymer sheet having electrical conductivity and being disposed in the longitudinal and transverse directions of an electroconductive substrate, so that the gasket has impact and vibration absorbing properties in addition to an adhesive property.
