To provide a repairing method of an electric-wiring through portion whereby its airtight performance can be recovered without any replacement of its module with new one.
In a repairing method of an electric-wiring through portion with the structure wherein passing a wire 11 through a metallic case, a sealing resin 3 is filled hermetically into the metallic case to provide a leak monitoring space portion 6 in the middle of the sealing resin 3, moving a module body 2 to expose a leak monitoring port 5 to the outside, the sealing resin 3 is filled hermetically into the leak monitoring space portion 6 from the leak monitoring port 5. Also, in this method, moving the module body 2 to expose the leak monitoring port 5 to the outside, the sealing resin 3 is once filled hermetically into the leak monitoring space portion 6 from the leak monitoring port 5, and thereafter, the sealing resin 3 is extracted from the leak monitoring space portion 6 before its curing to form films 4 made of the sealing resin 3 on both the inner walls of the leak monitoring space portion 6.
