PROBLEM TO BE SOLVED: To provide an electric conduction plug retaining airtightness and excellent in workability at assembly. SOLUTION: An insulator object 3 and a metal core wire 4 are contained inside a cylindrical connection metal fitting 1, and that 1 and the core wire 4 are fixed by using a holding member 5. Both the metal fitting 1 and the core wire 4 are made of metal, and management of dimensional tolerance is comparatively easy, so that they can be surely fixed by using the holding member 5. Therefore, since assembling can be processed without using an adhesive, workability is superior and possibility of defects occurrence is reduced, and furthermore, a plug is to be in a sealed state by elastic force of the holding member 5, hence, the electric conduction plug is achieved with excellent performance in retaining airtightness.
