Abstract
The thermal conductive sheet of the present invention includes a base sheet and, on one surface of the base sheet, a metal foil (C) that has a thickness of from 1 to 30% of a thickness of the base sheet. The base sheet includes a binder component (A) that exhibits elasticity at room temperature and a graphite powder (B) that has anisotropy, and the graphite powder (B) is oriented in a thickness direction.
