The present invention provides a highly reflective precoated aluminum alloy sheet that can be reduced in thickness and weight, can be manufactured at a reduced cost, and has excellent formability and reflection characteristics. A substrate 2 made of an aluminum alloy plate and a precoat layer 4 formed on one side or both sides of the substrate 2 are provided. At least one of the precoat layers 4 is formed in the base resin 41 with barium sulfate, titanium oxide, calcium carbonate, calcium sulfate, alumina, magnesium oxide, magnesium sulfate, zinc oxide, glass, aluminum nitride, boron nitride, silica, zirconium oxide, One or a plurality of highly reflective layers 40 containing a highly reflective material 42 made of one or more hollow glass beads are provided. The highly reflective layer 40 preferably uses a synthetic resin paint containing, as a main component, a synthetic resin having a number average molecular weight of 5000 to 50000 as the base resin 41.
