Abstract

PURPOSE:To improve thermal efficiency and durability by providing a heating part consisting of a metallized surface which heats a semiconductor element on the outside circumference along the end edge of an insulator tube and the end edge of a hollow groove continous with this. CONSTITUTION:A hollow groove 3a to be seated therein with a semiconductor element as well as small holes 3b which penetrate from the bottom surface 3a' of the groove 3a to the other end face and into which a pair of lead wires projecting from the semiconductor element are inserted are provided on the outside circumference near the end face of an insulator tube 3. A belt-like heating part 31 along the end edge of the tube 3 and the end edge of the groove 3a continuous with this is formed by a metallized surface consisting of a thin film of a heat resistant metal. A conducting circuit 31a is provided to connect the part 31 to an electric power source of the outside.
