PROBLEM TO BE SOLVED: To provide a multiple simultaneous solder-sealing tool that prevents current flowing in an electrical heating element from being increased, even if the number of simultaneous sealing is increased, and with little damages to the tool. SOLUTION: An electrical heating element is used, where the electrical heating element is arrayed in a comb shape, while a plurality of electrical heating element sealing parts are electrically connected in series, and a part following the electrical heating element sealing part is formed into a U shape for connecting to the next electrical heating element sealing part. The U-shaped part of the electrical heating element is retained by two insulation fixing pedestals. For the spacing between two fixing pedestals, the insulating fixing pedestal of one side is slidable on a work bench, so that expansion and contraction by the heat of the electrical heating element can be followed.
