1. A liquid ejecting head comprising:
a plurality of individual flow channels provided with nozzles;
a common supply flow channel through which a liquid is supplied to the plurality of individual flow channels;
a common discharge flow channel through which the liquid is discharged from the plurality of individual flow channels; and
a bypass flow channel that bypasses the plurality of individual flow channels and causes the common supply flow channel and the common discharge flow channel to communicate with each other, wherein
a combined flow channel resistance of the bypass flow channel and the plurality of individual flow channels is greater than a flow channel resistance of the common supply flow channel and is greater than a flow channel resistance of the common discharge flow channel.
