A carbon material having a continuous porous structure oriented to the stretching axis is provided, which carbon material can be used as a structural material excellent in interfacial adhesion. The porous carbon material has a continuous porous structure in at least a portion thereof, in which the continuous porous structure has an orientation degree measured by a small-angle X-ray scattering method or an X-ray CT method of 1.10 or more.

A carbon pyrolyzate material is disclosed, having utility as an adsorbent as well as for energy storage and other applications. The pyrolyzate material comprises microporous carbon derived from low cost naturally-occurring carbohydrate source material such as polysaccharides.
