Document Type and Number:
WIPO Patent Application WO/2018/235659
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a composite aluminum material that exhibits excellent adhesion between a support and a supported substance. This composite aluminum material has an oxide film-carrying aluminum base material, which has an oxide film on at least a part of the surface of the aluminum base material, and a supported substance supported on the surface of the oxide film-carrying aluminum base material, wherein the average thickness of the oxide film is not less than 1 nm but less than 100 nm, and the oxide film side surface of the aluminum base material has at least one type of relief structure selected from the group consisting of a relief structure that includes recessed parts having an average opening diameter of more than 5 μm but not more than 100 μm, a relief structure that includes recessed parts having an average opening diameter of more than 0.5 μm but not more than 5 μm, and a relief structure that includes recessed parts having an average opening diameter of more than 0.01 μm but not more than 0.5 μm.
