PROBLEM TO BE SOLVED: To provide a liquid feeding method and a liquid feeding device that can suppress an air bubble from being formed when feeding a liquid.SOLUTION: A liquid feeding device comprises: a preparation tank 2, a storage tank 3, first piping 11 extended to rise toward a downstream side of a flow passage, second piping 12 extended in a horizontal direction, third piping 13 extended to fall toward the downstream side of the flow passage, fourth piping 14, a valve 21, and a filling machine 4. The first piping is filled with a liquid until the liquid level in the first piping reaches the liquid level in the preparation tank by opening the valve without pressurizing the inside of the preparation, and the first piping is filled with the liquid by continuously pressuring the inside of the preparation tank up to first pressure. The second piping is filled with the liquid by closing the valve to an opening less than a full opening, and continuously pressuring the inside of the preparation tank until second pressure is reached, and the liquid in the second piping is made to flow in the third piping so as to push air in the third piping and fourth piping out to the side of the storage tank and also to pump the liquid to the storage tank.SELECTED DRAWING: Figure 1 【課題】送液する際に気泡が生じることを抑制することができる送液方法及び送液装置を提供する。【解決手段】調製タンク２と、貯留タンク３と、流路の下流側に向けて上昇するように延設された第１配管１１と、水平方向に延設された第２配管１２と、流路の下流側に向けて下降するように延設された第３配管１３と、第４配管１４と、バルブ２１と、充填機４とを備え、調製タンク内を加圧せずにバルブを開放して、第１配管内の液面が調製タンク内の液面と等しくなるまで第１配管内に液体を満たし、調製タンク内を第１圧力まで連続的に加圧することで、第１配管内を満液とし、バルブを全開よりも閉じた開度とし、第２圧力に達するまで調製タンク内を連続的に加圧することで第２配管を満液とし、第２配管から液体を第３配管内に流入させることで前３配管及び第４配管内の空気を貯留タンク側に押し出すとともに液体を貯留タンクに圧送する。【選択図】図１
