This steel-aluminium composite foil is provided with: a core layer provided with a steel layer, and an Al-containing metal layer formed upon the steel layer; and an Al layer stacked upon the Al-containing metal layer of the core layer. When viewed in a cross section having a cutting direction that is parallel with a thickness direction, dispersed Fe-Al alloy particles separated from the steel layer are included in the Al-containing metal layer. La présente invention concerne une feuille composite acier-aluminium comportant: une couche centrale dotée d'une couche d'acier et d'une couche métallique contenant de l'Al formée par-dessus la couche d'acier; et une couche d'Al superposée à la couche métallique contenant de l'Al de la couche centrale. Dans une vue en coupe suivant une direction de coupe parallèle au sens de l'épaisseur, des particules dispersées d'alliage Fe-Al séparées de la couche d'acier sont incluses dans la couche métallique contenant de l'Al.
