Provided is a joining aluminum coated material that has an adhesive layer on a surface thereof, and can achieve excellent adhesion strength and corrosion resistance even under severe use conditions while being chromium-free. Also provided are an aluminum coated material from which said joining aluminum coated material can be produced, and an aluminum resin composite material using said joining aluminum coated material. Disclosed is a joining aluminum coated material that has an adhesive layer on a surface thereof, wherein a silica-containing film formed on a surface of an aluminum material includes from 0.5 to 35 mass% of a silane coupling agent, and has a Si content of from 2 to 60 mg/m 2 , a P content of from 0.1 to 6.0 mg/m 2 , and a mass ratio P/Si between the P content and the Si content within a range of from 0.02 to 0.15. Also disclosed are an aluminum coated material from which said joining aluminum coated material can be produced, and an aluminum resin composite material obtained by using said joining aluminum coated material. |
