PROBLEM TO BE SOLVED: To provide a method of manufacturing a laminate with high accuracy which prevents the deterioration of parallelism between top and bottom of the laminate and the occurrence of collapsing layer stacking, which are caused by variation in thickness among sheets, and/or which are not affected by variation in thickness among sheets in manufacturing the laminate, by stacking multiple sheets and dowel crimping these layers into one plate body. SOLUTION: In the manufacturing method to form a laminate 5 by stacking multiple sheets 9 with dowel one by one in a die 4 using a punch 1 and dowel crimping layer-to-layer into one plate, it is equipped with an underhung pat 7 supporting the bottom side of the sheet 9 in parallel with the bottom face of a punch 1, a lower die guide 6 guiding the underhung pat 7 below the die vertically against the bottom face of the punch, a die 4 with a guiding face 4a vertically against the underhung pat 7, and a cylinder 8 moving the underhung pat 7 up and down.
