Liquid ejection head
11141982 · 2021-10-12 · ·

A liquid ejection head includes pressure chambers arranged in a first direction, a common channel, and a communicating portion communicating with the common channel and each of the pressure chambers. The common channel includes a supply portion, a return portion, and a connection portion connecting them in a second direction crossing the first direction. The liquid ejection head has a first vector directed from the supply portion via the connection portion toward the return portion and has a component in the second direction. The second vector is directed from the common channel via the communicating portion toward each of the pressure chambers and has a component in the second direction. The component in the second direction of the first vector and the component in the second direction of the second vector point in the same direction.
