たことを特徴とする自己復旧形成流素子。(1) An insulating cylinder having a through hole is placed inside an outer cylinder with both ends closed, and the through hole is filled with a current limiting member that is normally conductive and vaporizes due to overcurrent to perform a current limiting action. A first insulating cylinder having a first through-hole with a predetermined cross-sectional area and a second insulating cylinder having a through-hole having a smaller cross-sectional area than the through-hole of the first insulating cylinder are connected to the second insulating cylinder. The insulating tube is placed in the outer tube so as to be on one end side of the outer tube, and a first electrode placed at the other end of the outer tube is pressed against the first insulating tube to open the outer tube. A self-restoring forming flow element characterized in that a second electrode disposed at one end is made of a metal member with good thermal conductivity and is pressed against the second insulating tube. （２）第２の電極はクロム銅で構成したことを特徴とす
