PROBLEM TO BE SOLVED: To provide a switching element having nano gap electrodes which is capable of stable switching operation.SOLUTION: The switching element includes a first electrode 10 and a second electrode 20, and an interelectrode gap part 30 disposed between the first electrode 10 and the second electrode 20 and having a gap for causing a switching phenomenon of switching a resistance state upon the application of a predetermined voltage between the first electrode 10 and the second electrode 20. The first electrode 10 and the second electrode 20 include base parts 11, 21, respectively. The base part 11 of the first electrode 10 and the base part 21 of the second electrode 20 are opposite via a gap capable of generating a tunnel current. At least either of the first electrode 10 and the second electrode 20 includes low melting point parts 12, 22 comprising a substance having a lower melting point than a substance constituting the base parts 11, 21 in the region of opposition of the base parts 11, 21. 【課題】安定したスイッチング動作が可能なナノギャップ電極を備えるスイッチング素子を提供する。【解決手段】第１電極１０及び第２電極２０と、第１電極１０と第２電極２０との間に設けられ、第１電極１０と第２電極２０との間への所定電圧の印加により抵抗状態が切り替わるスイッチング現象を生じさせる間隙を有する電極間間隙部３０と、を備え、第１電極１０及び第２電極２０はそれぞれ、土台部１１，２１を備え、第１電極１０側の土台部１１と、第２電極２０側の土台部２１と、はトンネル電流を発生可能な間隔を隔てて対向しており、第１電極１０及び第２電極２０の少なくとも一方は、土台部１１，２１同士の対向部分に、土台部１１，２１を構成する物質よりも融点が低い物質からなる低融点部１２，２２を備えることを特徴とする。【選択図】図１
