サの断面図である。 FIG. 2 shows a completed capacitor that has undergone the process shown in FIG. 1 above, and has a cylindrical plastic film 6 and an elastic body 5 wrapped around a tightening material 7 such as a metal wire or plastic wire, and then tightened to seal the capacitor. FIG.
本考案のコンデンサは以上のようにして構成さ
れたものである。 The capacitor of the present invention is constructed as described above.

付けられて密閉されるので、密閉が容易で能率よ
く生産でき、気密性が著しく向上する、安価に生
産できるなどの効果がある。 Therefore, the capacitor element 1 is surrounded by a laminated plastic film, and the main part of the drawer lead 3 is tightened and sealed by the tightening material 7, so that sealing is easy and production can be carried out efficiently. It has the effects of significantly improving airtightness and being able to be produced at low cost.
第３図は引出リード３が絶縁被覆８を有する場

ツクフイルムを用いて、コンデンサ素子１を被覆
し加熱することにより封口部の締付がし易い。 In the above-mentioned embodiment, the cylindrical plastic film 6 was previously wound into a cylindrical shape, but it may be wound around the capacitor element 1 to form a cylindrical shape. Further, by covering the capacitor element 1 with a highly heat-shrinkable plastic film and heating it, the sealing portion can be easily tightened.
叙上のように本考案のコンデンサは、生産性お
よび気密性の面で極めて有利となり、工業的なら
びに実用的価値の大なるものである。 As mentioned above, the capacitor of the present invention is extremely advantageous in terms of productivity and airtightness, and has great industrial and practical value.
