An electrode structure for anodizing a surface of an aluminum base, comprising:
- an aluminum electrode which is to be in contact with the surface of the aluminum base;
- a fixing member for fixing the aluminum electrode on the surface of the aluminum base;
- an elastic member provided between the fixing member and the aluminum base;
- a lead wire which is electrically connected to the aluminum electrode at least under a certain condition;
- and
- a cover member which has an opening, the cover member covering at least part of the aluminum electrode, the cover member being tightly closed with the lead wire penetrating through the opening of the cover member.
A method for forming an anodized layer, comprising the steps of:
- providing an aluminum base;
- attaching an electrode structure to the aluminum base, the aluminum base including an aluminum electrode which is to be in contact with a surface of the aluminum base, a fixing member for fixing the aluminum electrode on the surface of the aluminum base, an elastic member provided between the fixing member and the aluminum base, a lead wire which is electrically connected to the aluminum electrode at least under a certain condition, and a cover member which has an opening, the cover member covering at least part of the aluminum electrode, the cover member being tightly closed with the lead wire penetrating through the opening of the cover member;
- and
- performing anodization with the surface of the aluminum base being in contact with an electrolytic solution.
