While avoiding the quartz fusion technique, an accurate and vacuum-tight electric leadthrough is provided which in addition is mechanically rigid. The electric conductor is fixed at the interior of a cell through an aperture by means of a ring of polytetrafluoroethylene in such a manner that the conductor is held in the center of the aperture. Over the ring and inside the aperture, a layer of cyano acrylate talcum cement is provided. Inside this layer in the aperture, a layer of a granular filler which is soaked with cyano acrylate adhesive is provided. Finally, the outermost part of the aperture is filled and sealed with a layer of cyano acrylate talcum cement.
