A liquid material filling device and method are provided which are intended to prevent air bubbles from remaining along an entire length of a flow passage extending from a liquid material reservoir (51) to a discharge port (53). The liquid material filling device includes a chamber (10) of an airtight structure, a pressure regulator (70) for regulating pressure in the chamber (10), and a control device (100). The liquid material is filled as follows. A negative pressure supply source (71) is communicated with a chamber communication pipe (90) and with a discharge device communication pipe (91) to reduce the pressure in the chamber (10) and pressure in an upper space of the reservoir (51) to a vacuum or a low pressure level close to a vacuum, and a resulted low-pressure state is maintained for a certain time to expel out air bubbles in the liquid material. The upper space of the reservoir (51) is then communicated with a gas supply port (93), thus allowing gas to flow into the relevant space and increasing the pressure in the relevant space to become higher than the pressure in the chamber (10) such that the liquid material within the reservoir (51) is filled into a discharge device (50). After communicating the upper space of the reservoir (51) with the inside of the chamber (10) and establishing a pressure equilibrium state, the upper space of the reservoir (51) is communicated with a gas supply port (92) to release the pressure.
