An ink jet recording head includes drive electrodes arrayed at fixed pitches on the surface of an elastic plate, a common lead-out electrode led from a common electrode formed on the surface of the elastic plate, the common lead-out electrode being arrayed extending in the direction of the arrays of the drive electrodes, while being spaced a fixed distance from the drive electrodes, the ends of the common lead-out electrode being connected to external, and piezoelectric vibration plates of which the reverse sides are in contact with the drive electrodes, and the first ends are continuous covering the common lead-out electrode. No disconnection is formed in the area of the piezoelectric vibration plates where the two groups of the piezoelectric vibration plates face, thereby ensuring a reliable bonding of the piezoelectric vibration plates and the elastic plate. |
