Vibration is prevented from being transmitted via a common ink chamber 8 or a fixed substrate 3. A porous member 11 is disposed between the common ink chamber 8 and a pressure generation chamber 9 so that a discharge liquid passes through the interior of the porous member 11 to move from the common ink chamber 8 to the pressure generation chamber 9. Vibration generated in one pressure generation chamber 9 is attenuated through the porous member 11 when the vibration is transmitted to another pressure generation chamber 9 via the common ink chamber 8; and thus, no cross-talk is generated. Furthermore, when piezoelectric vibrators 4 having different lengths are mounted on the same fixed substrate 3 and have the resonance frequencies different from each other, vibration is not transmitted to another pressure generation chamber 9 via the fixed substrate 3 and the piezoelectric vibrator 4; and therefore, the cross-talk is much less likely to be generated.
