Vibration is prevented from being transmitted via a common ink chamber or a fixed substrate. A porous member is disposed between the common ink chamber and a pressure generation chamber so that a discharge liquid passes through the interior of the porous member to move from the common ink chamber to the pressure generation chamber. Vibration generated in one pressure generation chamber is attenuated through the porous member when the vibration is transmitted to another pressure generation chamber via the common ink chamber; and thus, no cross-talk is generated. Furthermore, when piezoelectric vibrators having different lengths are mounted on the same fixed substrate and have the resonance frequencies different from each other, vibration is not transmitted to another pressure generation chamber via the fixed substrate and the piezoelectric vibrator; and therefore, the cross-talk is much less likely to be generated.
