PURPOSE:To shorten the manufacturing time and to reduce the cost by pressing the sealing part of a nozzle by pinching it between pressing members made of conductance body, then by flatly crushing the part thereof and by performing a resistance welding by electrifying the pressing members as well. CONSTITUTION:The inner part of a heat pipe 11 is held vacuous and connected to an actuation liquid pouring device as well and a nozzle 12 is pinched between a pair of pressing members 13. The part close to the base part of the nozzle 12 is flatly crushed by pressing both pressing members 13 forming roundness on the opposite faces and the presseing members 13 are electrified via a lead wire 14 as well to subject the overlapping part of the nozzle 12 to a resistance welding. The heat pipe is finally completed by removing the tip part from a cut part 15 by cutting the weld zone of the nozzle 12. Owing to performing the welding simultaneously with crushing the nozzle 12 the manufacturing process is shortened. Consequently the shortening of the manufacturing time and the cost reduction are enabled.
