Abstract
The present invention provides an electrical connection structure for an electrical connection with high density and reliability, and which is particularly superior in high frequency characteristics and prevents any leakage current at the contact. Preferred embodiment includes a dielectric film and a first conductor pattern having one or plural microconductor protrusions which is formed on dielectric film, an elastic member which is provided on the other side of dielectric film, thereby an electrical connection is accomplished by pressing a contacting surface of first conductor pattern by a force exerted through elastic member. The distance between microconductor protrusions may be changed during a contacting operation and microconductor protrusions will scratch a surface of a conductor to be contacted, e.g. a pad, a line pattern while a distance and thickness of compression are under control.
