1. A forming apparatus for a pouch-shaped case, the forming apparatus comprising:
a forming apparatus base having recesses configured to manufacture by pressing a lower receiving portion of the pouch-shaped case and an upper receiving portion of the pouch-shaped case continuously connected to the lower receiving portion, the lower receiving portion and the upper receiving portion together being configured to receive an electrode assembly therein;
a lower die of the forming apparatus; and
an upper die of the forming apparatus,
wherein the forming apparatus base comprises:
an upper surface start portion, the upper surface start portion defining a first end of the forming apparatus base, the upper surface start portion being inclined downwards at a predetermined angle relative to a lower surface of the forming apparatus base, the upper surface start portion being flat;
a proximal end side wall continuously connected to a distal end of the upper surface start portion of the forming apparatus base, the proximal end side wall extending downwards from the upper surface start portion;
a base lower portion continuously connected to the proximal end side wall, the base lower portion being inclined downwards at the predetermined angle relative to the lower surface, the base lower portion being flat;
a base side portion continuously connected to the base lower portion, the base side portion extending upwards perpendicularly from the base lower portion;
a base upper portion continuously connected to the base side portion, the base upper portion being inclined downwards at the predetermined angle relative to the lower surface, the base upper portion being flat;
a distal end side wall continuously connected to the base upper portion, the distal end side wall extending upwards perpendicularly from the base upper portion; and
an upper surface end portion, the upper surface end portion being continuously connected to the distal end side wall, the upper surface end portion being inclined downwards at the predetermined angle relative to the lower surface, the upper surface end portion being flat.
