1. An anisotropic graphite composite comprising:
(a) anisotropic graphite;
(b) a titanium-containing metal layer; and
(c) an inorganic material layer,
the (a) anisotropic graphite having graphite layers whose respective crystal orientation planes are parallel to an X-Z plane, given an X axis, a Y axis orthogonal to the X axis, and a Z axis perpendicular to an X-Y plane,
the anisotropic graphite (a) having a length in a direction parallel to the X axis of not less than 4 mm and not more than 300 mm,
the anisotropic graphite (a) having a length in a direction parallel to the Y axis of not less than 4 mm and not more than 300 mm,
the anisotropic graphite (a) having a thickness in a Z axis direction of not less than 0.5 mm and not more than 5.0 mm,
the anisotropic graphite (a), the titanium-containing metal layer (b), and the inorganic material layer (c) being stacked in this order in the Z axis direction and joined to each other,
an interface of the anisotropic graphite (a), at which the anisotropic graphite (a) is joined to the titanium-containing metal layer (b), having an interface roughness of not less than 2 μm and not more than 7 μm,
an interface of the inorganic material layer (c), at which the inorganic material layer (c) is joined to the titanium-containing metal layer (b), having an interface roughness of not less than 3 μm and not more than 10 μm.
