Beschreibung
Zusammenfassung:	A metal connection member provided with: a Mg alloy part, which has magnesium as a main component; a mating part, which has a more noble metal than magnesium as the main component and is to be connected to the Mg alloy part; and a chemical conversion coating film covering the surface straddling the boundary between the Mg alloy part and the mating part. Un élément de connexion métallique selon la présente invention comprend : une partie en alliage de Mg, qui comporte du magnésium en tant que composant principal ; une partie d'accouplement, qui comporte un métal plus noble que le magnésium en tant que composant principal et qui est destinée à être connectée à la partie en alliage de Mg ; et un film de revêtement de conversion chimique qui recouvre la surface couvrant la limite entre la partie en alliage de Mg et la partie d'accouplement. マグネシウムを主体とするＭｇ合金部材と、マグネシウムより貴な金属を主体として、前記Ｍｇ合金部材と接続される相手部材と、前記Ｍｇ合金部材と前記相手部材との境界を跨いで表面を覆う化成処理膜とを備える金属接続部材。
