To provide a surface structure of an aluminum-based member which can further improve heat insulating properties and heat shielding properties of the aluminum-based member. In an aluminum-based member 1 containing at least a silicon composition, a porous oxide film 2 is provided on a surface of the aluminum-based member 1, and the oxide film 2 is constituted to have at least a pore 2a extending from the surface toward an inside in a thickness direction of the oxide film 2 and a void 3a present inside the silicon composition 3 extending in a direction substantially orthogonal to the thickness direction of the oxide film 2.
A surface structure of an aluminum-based member containing at least a silicon composition, wherein a porous oxide film is provided on a surface of the aluminum-based member, and the oxide film has at least a pore extending from the surface toward an inside in a thickness direction of the oxide film and a void present inside the silicon composition extending in a direction substantially orthogonal to the thickness direction of the oxide film.
