Summary:To achieve, in a contact device used in a high-electrical capacity relay, an airtight terminal with which a more airtight contact device is achieved, and a relay contact device to which the airtight terminal is applied, and, at the same time, to provide a relay contact device improved in robustness of a sealing part due to a conventional configuration and further improved in reliability of airtightness.SOLUTION: An airtight terminal includes: a metal container 12 having a vent 11; a pipe lead 13 that is inserted into the vent; an insulation material 14 that seals the metal container and the pipe lead; and a terminal block 15 comprising a low-resistance metal which penetrates the pipe lead and is fixed to the pipe lead. The terminal block comprises at least a body part 16 and a head part 17. The head part has further a fixed section 18, the fixed section having an axis that is not arranged coaxially with the axis of the body part.SELECTED DRAWING: Figure 1 【課題】高電気容量のリレーに用いられる接点装置において、より気密性の高い接点装置を実現する気密端子および該気密端子を適用したリレー用接点装置を実現し、併せて従来構成に起因する封止部の頑健性を向上し、さらに、気密信頼性を向上したリレー用接点装置を提供する。【解決手段】通孔１１を有する金属容器１２と、この通孔に挿通したパイプリード１３と、金属容器とパイプリードとを封着する絶縁材１４と、パイプリードを貫通し該パイプリードに固着した低抵抗金属からなる端子台１５とを備え、記端子台は、少なくとも胴部１６と頭部１７とからなり、さらにこの頭部は固定部１８を有し、固定部の軸は、胴部の軸と同軸に配置されていない。【選択図】図１
