PROBLEM TO BE SOLVED: To provide a conductive glazed insulation tube to which, cementing operation can be easily applied, having a conduction part like cement hardly generating crack or exfoliation, having a preferable appearance around a joining part. SOLUTION: A ring-shaped shade part 31 having a hanging part 31a hanging down so as to surround a joining part 2 at the outer peripheral part of an upper insulation tube piece 3 is formed to the joining part of the conductive glazed insulation tube. Conductive glazes 3a, 4a, at the end part of upper and lower insulation pieces 3, 4 are electrically connected by filling conductive member 5 inside a concave part, open downward, formed by being surrounded by the hanging part 31a, and covering an exposed part 21a of a jointing glaze 21 by the conductive member 5.
