Fine structural body surface and method of producing the same

摘要

Described is a structural body including at least partially an aluminum member having on a surface an anodized film with micropores present, in which: the micropores have a coefficient of variation in pore size of 5 to 50%; and the micropores are each sealed with a metal. The structural body can generate localized plasmon resonance having a sufficiently large intensity and be produced at low cost through a simple production process, and having a large surface area.
