1. An apparatus for manufacturing an electrode body, the apparatus comprising:
a coater that applies a mixture paste including an electrode active material to a substrate that is configured to be a current collector;
a discharge slot arranged on the coater to discharge the mixture paste;
a collection magnet arranged on the discharge slot to remove and collect a metal object contained in the applied mixture paste from the applied mixture paste, wherein the collection magnet is opposed to an applied layer of the mixture paste formed on the substrate, and the collection magnet is arranged at a downstream side of the discharge slot in a transportation direction of the substrate that is continuously transported; and
an attraction magnet opposed to the applied layer of the mixture paste formed on the substrate and configured to attract a metal object that is not collected by the collection magnet so that when the mixture paste contains the metal object that is not collected by the collection magnet, the attraction magnet attracts the metal object that is not collected by the collection magnet so as to change a shape of a surface of the applied layer.
