Abstract
Proposed are a manufacturing method of an anodic oxide film structure, and an anodic oxide film structure. More particularly, proposed are a manufacturing method of an anodic oxide film structure, and an anodic oxide film structure, wherein production yield of the entire product can be improved by repairing a defective region to be made normal.
Claims2
A manufacturing method of an anodic oxide film structure, wherein an anodic oxide film plate comprises an anodic oxide film and a plurality of through-holes through the anodic oxide film, the anodic oxide film being formed by anodizing a base material and removing a remaining portion of the base material after the anodizing has been performed, the manufacturing method comprising:
- testing whether a defective through-hole among the plurality of through-holes in the anodic oxide film plate exists;
- and
- repairing the defective through-hole existing in the anodic oxide film plate by dividing the anodic oxide film plate into a plurality of divided plates and replacing a defective divided plate including the defective through-hole with a normal divided plate without including the defective through-hole,
- wherein the defective divided plate is one of the plurality of divided plates, and the normal divided plate is distinct from the plurality of divided plates.
