Abstract: In a discharge tube, a conductive ferrule is provided on an end portion of a glass tube. The ferrule includes a body that is to be mounted to the outer circumference of the glass tube and has a contact portion to be electrically conductively fixed to a relay connector (or a bearing device). Further included is a conductive portion that extends from the body so as to have elastic contact with an outer lead. The outer lead will not be under load due to the weight of the discharge tube, but the conductive portion solely has elastic contact therewith. Thus, stress concentration on the outer lead can be prevented.

Abstract: A process for producing an adhesive type heat-generation according to the present invention comprises an adhesive layer forming process 30 and a heating composition filling and the adhesive layer gathering process 60. In the adhesive layer forming process, the hydrous hydrophilic adhesive layer is spread and sandwiched between a release film and a base film while continuously feeding the release film and the base film from respective rolls to form the adhesive layer. In the heating composition filling and the adhesive layer gathering process 60, the base film is placed on the air-permeable film at its one side opposite to the adhesive layer, peripheral edges of the films are melt-bonded to form a heat-sealed peripheral edge and thus to form a pocket between the base film and the air-permeable film for containing the heating composition. At the same time, an adhesive of the adhesive layer is pushed and gathered inside the heat-sealed peripheral edge.
