Abstract
In a composite sealing material having an inner portion and a carbon outer portion, a bulk density of the carbon outer portion is set in a range of 0.3.about.2.0 g/cm.sup.3, preferably in a range of 0.5.about.1.5 g/cm.sup.3, or fiber members are mixed in the carbon outer portion, or an oil layer is arranged on the carbon outer portion, or an organic layer or an inorganic layer is arranged on the carbon outer portion, so as to improve sealing properties of sealing members formed by using the composite sealing materials.
