Abstract

The present invention provides a manufacturing device of a battery case including a first mold including a first space part having a shape corresponding to a storage part formed therein; a second mold including a second space part having a shape corresponding to the storage part and a through-hole communicating with the second space part formed therein, and coupled to the first mold with a laminate sheet interposed therebetween; and an air pressure regulator mounted in the through-hole in a state in which the first space part and the second space part are isolated from the outside, and increasing or decreasing an air pressure of the second space part through the through-hole to stretch and modify the laminate sheet into a shape corresponding to the first space part or the second space part.
