Liquid discharge head

A liquid discharge head comprising:

• a communication plate including a descender connected to a nozzle;
• a pressure chamber plate stacked on the communication plate, and including a plurality of pressure chambers each connected to the descender and arranged in an array direction;
• a piezoelectric element arranged in a position to overlap with the pressure chambers in a stacking direction of the communication plate and the pressure chamber plate;
• and
• a discharge common channel extending in the array direction, and connected to the plurality of pressure chambers,
• wherein the discharge common channel includes a first discharge portion formed in the pressure chamber plate, and a second discharge portion formed in the communication plate and connected to the first discharge portion,
• wherein the discharge common channel is configured to discharge liquid toward one side in the array direction, and
• wherein 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.
