PURPOSE: A manufacturing method of plastic element is provide to improve reliability of process because of not using wet etching method to remove a lower substrate, and to effectively solve a substrate deformation generated by free-standing in solution state. CONSTITUTION: A manufacturing method of plastic element comprises: a step of manufacturing an element on a layered structure substrate; a step of removing the layered structure substrate by separating layers of the substrate. The layered structure substrate is mica substrate. A plastic battery element manufactured by the method comprises: a plastic substrate(600), and a battery element(200) laminated on the plastic substrate. The battery element is manufactured in the mica substrate, and transferred to the plastic substrate. |
