Abstract
There is provided liquid discharging head having unit heads. Each of the unit heads includes: first piezoelectric layer, driving electrodes arranged on surface of the first piezoelectric layer and to each of which one of first and second potentials is to be applied, and common electrode. The common electrode includes: potential receiving part configured to receive one of the first and second potentials; and extending part extending in extending direction orthogonal to the first direction, so as to overlap with the driving electrodes in the first direction. The unit heads are arranged so that the common electrodes of the plurality of unit heads are adjacent to each other in second direction orthogonal to the first direction. The extending directions of two of the common electrodes adjacent to each other in the second direction are opposite to each other.
