Abstract
The aluminum alloy in the cross-section of the surface layer region of the aluminum alloy plate contains a compound containing one or more elements selected from the group consisting of silicon, magnesium, iron, copper, manganese, chromium, zinc, zirconium, and titanium, and aluminum. The number of fields of view containing the compound having an equivalent circle diameter of 5 μm or more out of 10 fields of view extracted from the cross-section is 3 or less. In the cross-section, the number density of the compound having an equivalent circle diameter of 1.5 μm or more and less than 5.0 μm is 0.0010 per μmor less, and the area ratio of the compound having an equivalent circle diameter of 0.5 μm or more is 0.1% or more and less than 1.0%.
