Disclosed is a technology that enables an elastic composite filter to have a capacitor to remove noise. The elastic composite includes a functional material layer; electrode patterns disposed on top and bottom surfaces of the material layer, respectively; and a conductive elastic member adhered onto the top electrode pattern, wherein the elastic member is coupled electrically and mechanically to the top electrode pattern to be used as an electrode, and the elastic member is in direct contact with a conductive object to provide elasticity.
