    摘要： A liquid discharging device where a liquid can be stably supplied to a liquid chamber and interference between liquid discharging sections caused by discharge of liquid drops can be reduced. The liquid discharging device has a liquid discharging head where liquid discharging sections are arranged on a circuit board. The liquid discharging sections each include an ink liquid chamber (12) for receiving a liquid to be discharged and a nozzle (18) for discharging the liquid in the ink liquid chamber (12). The liquid discharging device further has an individual flow path (20) provided at each liquid discharging section, communicated with the ink liquid chamber (12), and supplying the liquid to the ink liquid chamber (12), and has one common flow path (30) provided for the individual flow paths (20), communicated with all the individual flow paths (20), and sending the liquid to the individual flow paths (20). The common flow path (30) has a first common flow path (31) provided on the liquid supply source side and a second common flow path (32) provided adjacent to the individual flow paths (20) and having greater flow path resistance for the liquid than the first common flow path (31).
