To provide a cloth having excellent heat conductivity in thickness direction fully taking advantage of the heat conductivity of a light and compact fiber material and useful as a heat-dissipation sheet for a portable computer.

At least a part of pile yarns of a double pile cloth is composed solely of a highly heat-conductive fiber having a heat conduction coefficient of ≥10 W/mK and selected from a high-molecular weight polyethylene fiber, an aramid fiber, a polyarylate fiber, a polybenzazole fiber and a carbon fiber or composed of a blend of the highly heat-conductive fiber and glass fiber.
