Abstract

PURPOSE: Film layer porous body is formed in the surface of electric wire and even, when thermal expansion coefficiency between the electric wire and film layer does not meet each other, the film layer does not wipe off.
CONSTITUTION: A film layer 12 with porous body like zirconia powder is formed in the surface of an electric wire 11 and even when thermal expansion coefficiency between the electric wire and the film layer does not meet each other, the film layer is made not to be peeled off. Then, this electric wire 11 is inserted to the metal pipe and insulation material is charged between the pipe and the electric wire to form sheath heater.
