DEFORMABLE HEAT-TRANSMITTING BODY

PROBLEM TO BE SOLVED: To prevent a air layer from remaining between both members when mounting a heat-transmitting body between an exothermic member and a heat- receiving member of large area. SOLUTION: This heat transmitting body is an assembly of heat-radiation sheets 10, wherein being a small strip-like heat transmitting body, its thickness is constant while its width is wider at its central part, being gradually narrower toward the end part in the longitudinal direction. The heat-radiation sheet 10 is deformed when compressed, and so allocated in parallel that its larger part contacts a larger part of an adjoining heat-radiation sheet 10. On the assembly of heat-radiation sheets 10, a base film 12 is pasted on at least one surface, in advance, while peeling-off is allowed. The heat-radiation sheets 10 allocated in parallel with specified intervals on the base film 12 are flipped, pasted on a heat-receiving member, then the base film 12 is peeled off the heat-radiation sheets 10, and an exothermic member is placed on the heat-radiation sheets 10. After that, the heat-radiation sheets 19 are compressed between the exothermic member and the heat-receiving member, causing an air to be pressed out from the center part to both end parts.
