PROBLEM TO BE SOLVED: To fully inhibit a cross talk by using a damper wall. SOLUTION: The liquid transfer device comprises: a channel unit 2 in which two or more pressure chambers 33 and 36 corresponding to each nozzle hole 15a and 15b respectively are prepared in two lines in the inside of a channel from an ink supply port 8g to two or more nozzle holes 15a and 15b; and an actuator 3 which gives transfer pressure to ink in the pressure chambers 33 and 36, wherein the channel unit 2 includes: a common liquid chamber 30 which communicates with the ink supply port 8g and supplies ink to each pressure chambers 33 and 36 of two lines; and a damper wall 13a which faces to the common liquid chamber 30 and carries out elastic deformation, wherein the common liquid chamber 30 and the damper wall 13a are arranged so as to straddle the pressure chambers 33 and 36 of two lines by a plane vision.
