PROBLEM TO BE SOLVED: To provide a soft mold for forming a barrier rib, a manufacturing method of the barrier rib and lower panel, and a plasma display panel. SOLUTION: The manufacturing method of the soft mold includes a process for providing a metal mold 150 having a barrier rib pattern which repeats recessed parts and projected parts over one surface, a process for arranging a polymer sheet 190' so as to face to the metal mold, a process for forming the soft mold 190 having a reverse image of the barrier rib pattern on the one surface by pressurizing and transferring the metal mold in the polymer sheet, and a process for separating the soft mold from the metal mold. Thereby, a high-definition barrier rib pattern suitable for a high resolution display is provided with high form accuracy, and entire panel manufacturing processes can be simplified.
