Beschreibung
Zusammenfassung:	The present invention is a brazing sheet for flux-free brazing having a multilayer structure of two or more layers including one core material layer and one brazing material layer, in which the brazing material layer is positioned on one or both sides of the core material layer, the brazing material layer is made of an Al-Si-Mg-X brazing material containing: 0.05 to 2.0% of Mg, and 2.0 to 14.0% of Si, and further containing one or more of 0.01 to 0.3% of Bi, Ga, Sn, In and Pb, a total amount of Bi, Ga, Sn, In and Pb being 0.5% or less, an area ratio of MgO in an oxide film on a surface of the Al-Si-Mg-X brazing material is 2% or less, and an area ratio of a region with crystallinity among the MgO in the oxide film is 4% or less.
