Abstract: A carbon fiber composite material compact contains less of expensive carbon fibers, and the compact can therefore be used for general purposes which do not require highly superior physical properties. The carbon fiber composite material compact is produced by staking a first carbon fiber layer, a core layer, a second carbon fiber layer so as to form a laminate, and then compacting the laminate while impregnating an impregnable resin therein.
