1. A notching mold, configured to mold a non-coated portion when an electrode base material, in which an active material is applied to a surface of a collector, is input, wherein the non-coated portion, on which the active material is not applied, is formed on each of a first end and a second end of a coated portion, on which the active material is applied, the notching mold comprising:
a main mold comprising an upper mold and a lower mold, which are parallel to each other, wherein the upper mold and the lower mold are slidable close to or away from each other;
a first auxiliary mold mounted at a first side of the main mold and configured so that, when the electrode base material is input into the main mold, the non-coated portion on the first end of the electrode base material is disposed at a processible position, the first auxiliary mold comprising a first auxiliary upper mold coupled to the upper mold and a first auxiliary lower mold coupled to the lower mold; and
a second auxiliary mold mounted at a second side of the main mold and configured so that, when the electrode base material is input into the main mold, the non-coated portion on the second end of the electrode base material is disposed at a processible position, the second auxiliary mold comprising a second auxiliary upper mold coupled to the upper mold and a second auxiliary lower mold coupled to the lower mold.
