<P>PROBLEM TO BE SOLVED: To provide a deaeration method, a deaeration device and a droplet-discharging device for liquid piping that can certainly deaerate without wasting a liquid even when bubbles come intermittently. Ž<P>SOLUTION: The deaeration device includes an inlet side liquid main pipe 102 connected to the inlet side of a T-joint 101, an outlet side liquid main pipe 103 connected to the outlet side of the T-joint 101, an upward deaeration pipe 104 connected to the branch side of the T-joint 101, a deaeration valve 105 installed on the deaeration pipe 104 and a bubble detecting sensor 107 attached to the inlet side liquid main pipe 102. The deaeration valve 105 is opened before the bubbles B detected by the bubble detecting sensor 107 reach the outlet side liquid main pipe 103 to introduce the function liquid with the bubbles B which flows from the inlet side liquid main pipe 102 to the outlet side liquid main pipe 103, to the deaeration pipe 104.
