An expanded-graphite sheet whose thermal conductivity in its surfacewise directions is relatively uniform and higher than its thermal conductivity in its perpendicular direction can be produced efficiently at relatively low cost. Because the expanded-graphite sheet is made of expanded graphite alone and has thermal conductivity in parallel direction of 350 W/(mK) or more, its thermal conductivity in parallel direction is much higher than its thermal conductivity in a perpendicular direction; therefore, it is suitable for the conduction and diffusion of heat. Besides, the expanded-graphite sheet can be produced easily, in a short time, efficiently, at relatively low cost.

The present invention improves the strength of the bottom (net) of the jig and makes it more difficult and unlikely for deviation of the mesh to occur. A workpiece is loaded on the net (2) of the heat treat furnace jig (hereinafter, heat treatment furnace jig). In the net (2), a first strand (10), a second strand (20) and a third strand (30) are in contact at a contact point (X1). Near the contact point (X1), the second strand (20) overlaps the first strand (10) from above and the third strand (30) overlaps the first strand (10) from below. As a result, the first strand (10) is held between the second strand (20) and the third strand (30) in the up/down directions.
