Abstract

PURPOSE:To ensure electrical conductivity in a heat-insulataing material used for space navigation bodies by accommodating an electrically conductive spring of thin wire diameter having a large number of coils and a resulting long heat conduction path into a hollow, cylindrical heat-insulating material body. CONSTITUTION:A good conductor spring 1 of thin wire diameter which is electrically conductive and has a large number of coils and a resulting long heat conduction path, is connected to a hollow cylindrical heat-insulating material body 2 made of fibrous glass reinforced plastics, etc., and the tips of the spring 1 are projected from both faces of the heat insulating material body to form a desired heat-insulating material. The good conductor spring 1 is brought into contact with material bodies 3, 4 under pressure by its elasticity to ensure the electrical conductivity between the material bodies 3, 4.
