A heat radiation sheet having high heat-radiation property and excellent handleability and having sheet properties permitting the sheet to cope with changes in use temperature thereof. Also provided is a heat radiation device using the sheet. The heat radiation sheet comprises: a binder component comprising: (A) a thermoplastic rubber component; (B) a thermosetting rubber component; and (C) a thermosetting rubber curing agent crosslinkable with the thermosetting rubber component (B); and an anisotropic graphite powder oriented into a specified direction in the binder component.

Heat radiation sheet and heat radiation device

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.

Thermal conductive sheet, method of producing thermal conductive sheet and heat releasing device

A fuel-cell separator comprising a resin and an electric conductor dispersed in the resin is produced by thermally molding a mixture comprising the electric conductor and the resin.
