Liquid ejection head

A liquid ejection head comprising:

• a supply manifold including a supply port through which liquid is supplied from an exterior;
• a return manifold including a return port through which liquid is discharged to the exterior;
• a plurality of individual channels each connected, at an upstream end thereof, to the supply manifold, each of the individual channels communicating with a corresponding one of a plurality of nozzles and including an individual throttle channel;
• and
• a connecting throttle channel through which adjacent ones of the individual throttle channels communicate with each other, the connecting throttle channel including a communication port in communication with the return manifold,
• wherein the connecting throttle channel has a channel resistance less than or equal to a channel resistance of each of the individual throttle channels,
• wherein the individual throttle channels include return throttle channels, each of the return throttle channels communicating with a corresponding pressure chamber communicating with the corresponding one of the nozzles, and
• wherein adjacent ones of the return throttle channels communicate with each other through the connecting throttle channel.
