A pouch-shaped battery case shaping apparatus includes a die having an open recess sized to correspond to an electrode assembly, a punch configured to draw a sheet into the open recess and thereby shape the sheet, a holder configured to fix ends of the sheet to the die during drawing of the sheet, and a lubricant supply unit configured to supply a lubricant to the sheet to minimize surface damage to the sheet due to the drawing of the sheet. A pouch-shaped battery case manufacturing process uses the pouch-shaped battery case shaping apparatus to shape the sheet.
