PURPOSE:To improve high frequency characteristics of a lightning surge protective circuit by employing a strip conductor rising from a substrate mounting an arrester and then drooping toward the substrate in which the widths of the rising part and the drooping part become narrower as the gap between the substrate becomes narrower. CONSTITUTION:A strip conductor 30 rises against a substrate 20 from an end part 31 and then droops toward an end part 32. In the central part of the strip conductor 30, the lead wire 25 of the other electrode of an arrester ARR penetrates and is electrically bonded to the strip conductor 30 through soldering. The strip conductor 30 is formed narrower as the height of the insulating substrate 20 decreases so that the inductance increases as the capacity increases thus achieving impedance matching. |
