<p><P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a heat-generating sheet, capable of stably manufacturing a heat-generating sheet having desired quality by preventing an application liquid from being applied on an unwanted portion. <P>SOLUTION: The method is used to manufacture a heat-generating sheet 10 including a sheet-like heat-generating body 2 formed by applying an application liquid containing an electrolyte to a sheet-like intermediate body 2A containing an oxidizable magnetic metal powder and a fibrous material, and sheets 11A, 12A for covering both the surfaces of the body 2. The manufacturing method has: a first step of applying the application liquid to a plurality of intermediate bodies 2A while transporting them by a first transport means 4 in a state where the intermediate bodies 2A are approximated to a flow direction; a second step of transferring the sheet-like heat-generating body 2 obtained by application of the application liquid to a second transport means 6 having a transport speed higher than that of the first transport means by using attraction of magnetic force of a magnet 62, and in the transfer, expanding the intervals of the heat-generating bodies 2 in the flow direction; and a third step, after the second step, of merging the sheet 12A to a surface opposite to a surface facing the second transport means 6 in the heat-generating body 2. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
