Abstract
A method of stacking a green sheet, where, in rolling up a support sheet on which a multilayer unit including a green sheet and/or electrode layer is formed, the multilayer unit can be easily unrolled without adhering to the back surface of the support sheet, and in stacking the multilayer unit, the support sheet can be easily separated from the multilayer unit. On the surface 20a of the support sheet 20 is stacked a multilayer unit U1 composed of an electrode layer 12a and/or green sheet 10a to form the support sheet with the laminated unit. Then, the support sheet 20 with the laminated unit is rolled up to form a rolled body R. The rolled body R is unrolled, the support sheet 20 with the multilayer unit is placed on a layer on which the support sheet is to be placed, the support sheet 20 is separated from the laminated unit U1, and the laminated unit U1 is stacked. On the back surface 20b of the support sheet 20 is applied separation-facilitating surface treatment with a width equal to or greater than the width of the multilayer unit U1, and an adhereable portion 23 where the separation-facilitating surface treatment is not applied is also formed on the back face 20b.
