Abstract
A liquid discharging head includes: individual channels; a first common channel; and a second common channel Each of the plurality of individual channels includes: a pressure chamber, a nozzle, a connecting channel, a first communicating channel, and two second communicating channels. A first vector of the first communicating channel has an orientation from one end to the other end of the first communicating channel. Respective second vectors of the two second communicating channels have orientations, each of the orientations being from one end to the other end of one of the two second communicating channels along an extending direction of the two second communicating channels. The first communicating channel is arranged, with respect to the nozzle, on one side in a second direction orthogonal to the first direction, and the two second communicating channels are arranged, with respect to the nozzle, on the other side in the second direction. Each of the orientation of the first vector and the orientation of the second vector includes an orientation component from the one side toward the other side in the second direction.
