| 摘要 | It is possible to obtain a graphite film with its shape controlled, by performing a sag controlling step of controlling temperatures of a polymer film at both widthwise ends and a temperature of the polymer film in a widthwise middle portion within a temperature range from a starting temperature of thermal decomposition of the polymer film to a sag controlling temperature of the polymer film. | ||

| 主权项 | 1. A graphite film having i) a sag resulting from different lengthwise lengths of the graphite film across a width of the graphite film, the sag formed in a shape such that the graphite film is continuously more sagging in a center portion of the graphite film than at each edge portion of the graphite film, and ii) camber of less than 10 mm at said each edge portion of the graphite film, in accordance with JIS C2151, wherein the center portion of the graphite film represents a portion located at an equal distance from both of ends of the graphite film in a width direction, and the ends of the graphite film in the width direction are defined as the edge portion of the graphite film. | ||
