To provide a carbon fiber composite effective even for an intractable skin ulcer generated in a bedridden patient, capable of recovering patient's health and discharging a large amt. of negative ions to keep user's health, and a bedding article using the same.

A carbon fiber composite comprises a planar material formed from activated carbon fibers having a large number of micropores and obtained by laminating high temp. combustion carbon fibers 4 produced by burning raw material fibers at 900-1,300°C in a non-oxidizing atmosphere and low temp. combustion carbon fibers 5 produced by burning raw material fibers at 600-700°C in a non-oxidizing atmosphere.
