Abstract
An anti-reflection structure body comprises a base member which is made of glassy carbon and at a surface of which is formed an anti-reflection structure including a cluster of minute projections each having a diameter that contracts towards a tip thereof. The minute projections preferably have an average height of from 200 nm to 3000 nm and an average maximum diameter of from 50 nm to 300 nm, and an average pitch of from 50 nm to 300 nm. An anti-reflection structure body which is easily produced, capable of achieving an anti-reflection effect near to non-reflection, and capable of providing the minute structure even to a member having a high melting point such as quartz glass or the like by transfer or the like can be provided.
