A liquid delivering method and a liquid delivering device are provided, which solve the prior art problems including damages to a plunger and a valve seat caused by abutting, the exchange of damaged plungers and valve seats, and the mixing of a damaged member or the like into a liquid material to melt therein. A liquid material delivering method comprises the steps of advancing at high speed a liquid material delivering plunger with its distal end surface closely contacted with the liquid material, and subsequently abruptly stopping plunger driving means, thereby applying an inertial force to the liquid material to deliver the latter. A liquid delivering device comprises a tubular metering section, a plunger internally contacting the metering section, a nozzle having a delivery port, a first valve for establishing communication between the metering section and the nozzle, a storage container for storing a liquid material, a liquid material feed valve (second valve) for establishing communication between the storage container and the metering section, wherein the inner diameter of the metering section is substantially equal to the diameter of a through hole formed in a valve member of the first valve.
