Abstract:
A liquid discharge head, includes an individual channel, and first and second common channels. The individual channel includes: a nozzle; a pressure chamber; a connection channel; a first communication channel; and a second communication channel. A first vector is defined such that a starting point and ending point are located on the connection channel, and a second vector is defined such that a starting point and an ending point are located on the second communication channel. A first angle formed by a projection vector of the first vector onto the first plane and a projection vector of the second vector onto the first plane is less than 90°. A second angle formed by a projection vector of the first vector onto the second plane and the second vector is less than 90°.
