To provide a method which can firmly join conductive glazed insulating tubes with each other while electrical conductivity is being produced between respective conductive glazes.
The joining end faces of conductive glazed insulating tubes 1 and 1 are formed into a V-shape in cross section each along their entire circumferences, conductive glaze 2 is applied to one portion of the joining end face at the outer circumferential surface side over to a width (w) to the extent of 1/8 to 1/2 of the thickness (t) of the conductive glazed insulating tube 1, and the other portion of the joining end face is coated with connecting glaze 3 so as to be baked. As a result, the conductive glaze 2 is extended over to the outer circumferential surface of the joining end face, and this portion thereby enables electrical conductivity to be produced between the conductive glazes of the upper and lower conductive glazed insulating tubes 1 and 1.
