The present invention relates to a method for manufacturing an NFC antenna, which can manufacture an NFC antenna in a small thickness to achieve miniaturization and reduce raw materials and costs, and an NFC antenna manufactured thereby. The method for manufacturing an NFC antenna according to the present invention comprises: a first step of laminating a polyimide film on a metal layer of a substrate; a second step of forming an antenna circuit pattern image by disposing resist, whose some areas are removed, on the top of the polyimide film and irradiating light from above the resist to expose the polyimide film; a third step of forming an antenna printed circuit by etching the metal layer portion of the substrate, which is exposed to the surface, after developing the uncured portion of the polyimide film, in which the antenna circuit pattern image is not formed; and a fourth step of forming the antenna printed circuit on ferrite by attaching the ferrite to the substrate and the antenna printed circuit and separating the substrate from the ferrite. |
