To provide an impact press working device that can sufficiently use impact force for press working, can efficiently perform press working, and requires less equipment investment, despite a press working device using impact force.SOLUTION: An impact press working device 1 that performs press working on a plate-like member w by applying an impact to the plate-like member w via a first pressure application unit 20 and a second pressure application unit 30 disposed at positions opposite to each other with the plate-like member w between them, includes: the first pressure application unit 20 having a first pressure application device 21 disposed on one-surface side of the plate-like member w; the second pressure application unit 30 having a second pressure application device 31 disposed at a position opposite the first pressure application device 21 with the plate-like member w between them; and impact application means 40 that applies an impact to the plate-like member w from both surfaces thereof via the first pressure application unit 20 and the second pressure application unit 30.SELECTED DRAWING: Figure 1
