Discussed is a notching apparatus and method for a secondary battery. The notching apparatus includes: a notching unit notching a portion of an electrode that is continuously supplied; a drying unit drying the electrode while the electrode discharged from the notching unit passes therethrough; and a collecting unit collecting the electrode discharged from the drying unit, wherein the drying unit includes a heating body provided with a drying space that is a passage through which the electrode passes therein, and lamp parts mounted on the heating body to irradiate infrared rays onto a surface of the electrode while the electrode moves through the drying space.

Discussed is an including a transfer unit transferring an electrode sheet having a plurality of notching grooves formed in a side surface thereof to a cutting point via a measuring point, wherein, when a front notching groove which is disposed at a front end in the electrode sheet is passing through the cutting point, a notching groove disposed in a rear end of the front notching groove is configured to pass through the measuring point; a detection unit at the measuring point to detect the notching groove passing through the measuring point and generating a notching groove detection signal; and a cutting unit at the cutting point to cut the electrode sheet according to the notching groove detection signal generated by the detection unit.
