<p>PROBLEM TO BE SOLVED: To provide a method for manufacturing a sheathed thermocouple or a sheathed heater capable of efficiently and inexpensively manufacturing a high quality product without generating insulation breakdown at the time of use, capable of surely performing dehumidifying treatment of even a long sheath by a space-saving heating and drying device, capable of suppressing even an energy cost, capable of efficiently performing the dehumidifying treatment in a short time with a high dehumidifying effect, and also capable of enhancing a degree of freedom of the manufacturing design.SOLUTION: When sheath cables are coupled, the sheath end parts are coupled to each other after humidity kept between insulators 4 inside the sheath cable 2 is dehumidified to the outside from the open ends of the sheath end parts 2a, 3a by partially heating a region of the area 2R having a prescribed length from each sheath end part 2a by an electromagnetic induction heater 6, and the whole sheath cable is not put into a heating furnace for dehumidification as in the past, but only the area of the sheath end part 2a is partially heated by the electromagnetic induction heater 6 for efficient dehumidification.</p> |
