Liquid ejection head
A liquid ejection head includes a supply manifold, a return manifold, a plurality of individual channels, and a connecting throttle channel. The supply manifold includes a supply port through which liquid is supplied from an exterior. The return manifold includes a return port through which liquid is discharged to the exterior. Each individual channel is connected, at an upstream end thereof, to the supply manifold and, at a downstream end thereof, to the return manifold. Each individual channel communicates with a corresponding one of nozzles and includes an individual throttle channel. Through the connecting throttle channel, adjacent ones of the individual throttle channels communicate with each other. The connecting throttle channel has a channel resistance less than or equal to a channel resistance of each individual throttle channel.
