In order to provide a liquid material discharge apparatus which can easily adjust a movement speed of a plunger and a method for the same, the liquid material discharge apparatus includes a liquid chamber (50) which communicates with a discharging port (11) and to which a liquid material is supplied; a plunger whose rear end portion has a piston (33) and whose front end portion moves forward and rearward inside the liquid chamber (50); an elastic body (47) which applies a biasing force to the plunger; and a pressurizing chamber (49) in which the piston (33) is arranged and to which compressed gas is supplied. The liquid material is discharged through the discharging port (11) by causing the plunger to move forward fast, the elastic body (47) biases the plunger in a rearward movement direction, and the compressed gas supplied to the pressurizing chamber (49) applies a driving force to the piston (33) to cause the plunger to move forward. The liquid material discharge method uses the liquid material discharge apparatus. |
