To reduce conduction failure due to freezing.SOLUTION: A contact device A1 comprises a fixed terminal 1, a movable member 11, a restricting member 12, and heat transfer structure 16. The fixed terminal 1 has a fixed contact 13. The movable member 11 has a movable contact 14, and moves between a closed position in which the movable contact 14 contacts the fixed contact 13 and an open position in which the movable contact 14 separates from the fixed contact 13. The restricting member 12 contacts the movable contact 14 when the movable member 11 is in the open position. The heat transfer structure 16 transfers the heat from the movable contact 14 when the movable member 11 is in the open position to the fixed terminal 1 through a thermal path including at least the restricting member 12.SELECTED DRAWING: Figure 1 【課題】凍結による接点の導通不良を低減する。【解決手段】接点装置Ａ１は、固定端子１と、可動部材１１と、規制部材１２と、熱伝達構造１６と、を備える。固定端子１は、固定接点１３を有する。可動部材１１は、可動接点１４を有し、可動接点１４が固定接点１３に接触する閉位置と可動接点１４が固定接点１３から離れる開位置との間で移動する。規制部材１２は、可動部材１１が開位置にあるときに可動接点１４に接触する。熱伝達構造１６は、少なくとも規制部材１２を含む熱経路を通して、可動部材１１が開位置にあるときの可動接点１４からの熱を固定端子１に伝達する。【選択図】図１
