An apparatus for forming a pouch-shaped secondary battery case is provided. The apparatus for forming a pouch-shaped secondary battery case includes a die having a forming recess formed therein, a punch configured to be brought into tight contact with an inner surface of the forming recess while moving upwards and downwards above the die, and a pouch sheet fixing unit configured to fix an edge of the pouch sheet while moving upwards and downwards above the die. The punch is provided with a plurality of air channels configured to blow outside air in a direction toward the forming recess or to suction air. The apparatus is capable of determining whether a pouch sheet is defective and preventing cracks from being formed in a receiving recess. A forming method using the same is also provided.

A method for manufacturing an optical element, the method including: heating an optical element material by suspending it in a gas; supplying the heated optical element material from a direction which intersects a central axis interconnecting centers of a first mold and a second mold to a space between molds in a non-contact state, the space between molds being a space between the first mold and the second mold; pressurizing the optical element material supplied to the space between molds by the first mold and the second mold; and cooling the pressurized optical element material.
