PROBLEM TO BE SOLVED: To provide a liquid discharge device that can achieve both improvement in sealability in a surrounding region of each communication hole of a vibration plate to be connected with a second flow path structure and securement of a region in which wiring pulled out from each piezoelectric device is arranged.SOLUTION: In a vibration plate are formed a plurality of communication holes 42 for communicating reservoirs of reservoir forming members 23 with a plurality of pressure chambers 26 respectively of flow path forming members 21. In surrounding regions of the plurality of communication holes 42 of the vibration plate are provided annular wall portions 60 that surround the plurality of communication holes 42 respectively. The reservoir forming members 23 are joined to surrounding regions in which the plurality of annular wall parts 60 of the vibration plate are provided. At least portions of the plurality of annular wall portions 60 are conductive wall portions 61 having conductive portions 62, and a conductive portion of one conductive wall portion 62 constitutes a part of a portion that connects a piezoelectric device 36 to a driving contact point 40 of a single driving wiring 35. |
