Provided is a carbon structure having a three-dimensional shape containing nano-carbon structures, wherein the nano-carbon structures have at least one structure from among a petal-like structure, in which flaky carbon having a graphene framework and a thickness of less than 20 nm is fixed in a petal-like shape, and an uneven structure formed by a collection of seed-like structures having a size of 1 to 100 nm. The carbon structure has favorable shapability and excellent durability in high radiation fields, and is effective as a reflective material for cold neutrons and very cold neutrons, the reflective material being capable of increasing the strength of the cold neutrons and very cold neutrons by coherent scattering.
