An electrical connection structure is provided. The electrical connection structure includes a through hole, a first pad, a second pad and a conductive bridge. The through hole has a first end and a second end. The first pad at least partially surrounds the first end of the through hole and is electrically connected to a first circuit. The second pad is located at the second end of the through hole and is electrically connected to a second circuit. The conductive bridge is connected to the first pad and second pad through the through hole, thereby making the first and second circuits electrically connected to each other.
