According to one embodiment of the present invention, a pneumatic launching device comprises: a gun barrel having one or more pressure holes; a pressure providing part which can be in fluid communication with the gun barrel through the pressure hole; a gas supply port formed in the pressure providing part and receiving gas from the outside; a sealing member fixed to the gun barrel to block a gap between a loaded projectile and the gun barrel; and a first trigger port connected to one end of the gun barrel to apply a pneumatic pressure to the loaded projectile. Therefore, an objective of the present invention is to provide the pneumatic launching device for reducing friction between the projectile and the gun barrel.
