摘要： An improved electrical heating molded-element or unit in which a heating wire is embedded or confined in one side of a fibrous layer formed by molding inorganic fibers into a given thickness, characterized in that a portion of said element or unit in the vicinity of the embedded heating wire is treated to provide a zone in which the density, heat conductivity and fire resistance are greater than those of the remainder. With this electrical heating molded-element or unit, it is possible to extract effectively the amount of heat generated by heating wire. This element or unit can be used over an extended period of time with safety but without causing local disintegration thereof owing to the expansion or contraction of the heating wire.
