PROBLEM TO BE SOLVED: To provide a method for manufacturing a support body having a structure in which a support substrate and metal foil can be easily separated and the like.SOLUTION: A method for manufacturing a support body includes the steps of: arranging an adhesive force adjustment layer for adjusting a contact area of a support substrate and a peeling layer in a predetermined region excluding an outer peripheral part on the support substrate; and arranging metal foil in which the peeling layer is formed on one surface thereof on the adhesive force adjustment layer and the outer peripheral part of the support substrate in the state in which the peeling layer is oriented to the side of the support substrate, and temporarily bonding the outer peripheral part of the support substrate and the peeling layer in a peelable manner. In the step of temporary bonding, the support substrate and the adhesive force adjustment layer are bonded, and the peeling layer and the adhesive force adjustment layer contact with each other without bonding.
