Abstract:
There is provided a liquid discharge head including: a communication plate formed with a descender connected to a nozzle, a pressure chamber plate including a plurality of pressure chambers aligning in an array direction, a piezoelectric element, and a discharge common channel. The discharge common channel extends in the array direction, is connected to the plurality of pressure chambers, and has a first discharge portion and a second discharge portion. The discharge common channel is configured to discharge liquid toward one side in the array direction. The second discharge portion includes an expansion portion to expand beyond the first discharge portion in a width direction orthogonal to the stacking direction and to the array direction.
