An apparatus for manufacturing a battery cell for processing a sealing part of a battery cell, the sealing part being formed on one side of a body part in which an electrode assembly is accommodated, comprising:

• a support unit including a first support portion and a second support portion supporting the battery cell in different directions;
• a pressing unit configured to move toward the support unit to heat and bend the sealing part;
• and
• a guide unit configured to guide rotation of the second support portion,
• wherein the pressing unit and the second support unit are connected to the guide unit, and
• wherein the guide unit includes a guide groove that is formed spaced apart for the rotation axis and having have a curvature corresponding to a rotation path of the guide unit.
