The present invention relates to a battery cell having a venting structure using taping, and more specifically, to a battery cell in which an electrode assembly structured so that a separation film isinterposed between an anode and a cathode is embedded in a battery case, the battery cell comprising: the battery case having a first case and a second case, wherein the first case and/or the secondcase is provided with a housing portion in which the electrode assembly is installed, wherein thermal fusion outer edge parts are formed on the outer edge area of the housing portion to seal the housing portion; an anode lead and a cathode lead, each of which protrudes out of the battery case; and the electrode assembly which is housed inside the battery case, and which has a structure comprisingelectrode tabs protruding from the end of one side are coupled to the anode lead and the cathode lead, wherein a sealing reinforcement tape is adhered to a portion of the thermal fusion outer edge parts so as to surround the outer edge end part of same, so that gas generated from inside the housing portion during charging and discharging of the battery cell can be discharged to the outside of thehousing portion through the thermal fusion outer edge parts of venting inducing portions to which the sealing reinforcement tape is not adhered.
