To provide a plate manufacturing device capable of adjusting a sheet having a different thickness part into a sheet with uniform material properties by annealing, and preventing any distortion by heating.
The sheet manufacturing device 10 comprises a rolling device 12 for forming a different thickness part different in thickness of a sheet by rolling the sheet, and a heating device 13 for annealing the rolled plate. The heating device 13 comprises first to third linearly heating means 101, 102 and 103 for extending the sheet in the sheet width direction to linearly heat the plate, a heat source moving means 104 for moving these first to third heating means in a range of the length of the different thickness part corresponding thereto, a condition setting means 26 for setting the heating condition according to the thickness of the different thickness part, and a control means 27.
