A pouch shaping apparatus comprising:

• a support unit configured to allow a laminate sheet to be disposed on an upper surface thereof;
• a stripper located above the support unit, the stripper configured to be movable upwards and downwards, the stripper also configured to press and fix an outer periphery of the laminate sheet disposed on the upper surface of the support unit when moved downwards;
• and
• a punch located above the support unit, the punch configured to be movable upwards and downwards in a first direction, the punch also configured to form an electrode assembly receiving portion in the laminate sheet while inserted into a shaping portion located at a center of the support unit when moved downwards, wherein
• the support unit comprises an upper support and a support plate, and
• the pouch shaping apparatus comprises a core member located between the upper support and the support plate, the core member having a predetermined thickness and configured to support the upper support while spacing the upper support and the support plate apart from each other to create a gap along the first direction between the upper support and the support plate such that the upper support does not move along the first direction but deforms along the first direction away from the core member.
