Summary:PROBLEM TO BE SOLVED: To provide an isotropic graphite material having a high bulk density, capable of suppressing generation of a crack, and to provide a production method capable of producing easily such an isotropic graphite material.SOLUTION: The isotropic graphite material is molded by subjecting spherical graphite and/or agglomerate graphite to isotropic pressurization, and preferably has a bulk density of ≥1.5 g/cm. In the production method, the isotropic graphite material is molded by subjecting the spherical graphite and/or the agglomerate graphite to isotropic pressurization. The spherical graphite and/or the agglomerate graphite preferably has a tap density of ≥0.8 g/cmand a volume average particle size of 8-50 μm.
