A heat radiation sheet having high heat-radiating properties and excellent handleability and having sheet properties which enable the sheet to cope with changes in use temperature. Also provided is a heat radiation device employing the sheet. The heat radiation sheet comprises: a binder ingredient obtained from a thermoplastic rubber ingredient (A), a thermosetting rubber ingredient (B), and a thermosetting-rubber hardener (C) capable of crosslinking the thermosetting rubber ingredient (B); and anisotropic graphite particles oriented in a certain direction in the binder ingredient. |
