Abstract:
A liquid discharge head includes a stacked body formed by plates stacked in a first direction, and having a liquid channel. The liquid channel includes: individual channels which include nozzles and pressure chambers communicating with the nozzles, respectively, and which are aligned in a second direction orthogonal to the first direction; a first common channel extending in the second direction and communicating with the individual channels; a second common channel extending in the second direction and communicating with the individual channels; first throttles each connecting one of the individual channels and the first common channel; and second throttles each connecting one of the individual channels and the second common channel. The plates include: a nozzle plate having the nozzles; a pressure chamber plate having the pressure chambers; a first common channel plate having the first common channel; and a second common channel plate having the second common channel.
