Liquid ejecting head

摘要

A liquid ejecting head includes a flow path unit that has a nozzle line formed by a plurality of nozzles and includes a flow path communicating with the nozzles, a head case that forms a shared liquid flow path for supplying a liquid to the flow path of the flow path unit and is connected with the flow path unit, and a sheet-like heater that is mounted on a side surface of the head case and has a continuous heat-generatable heating element folded multiple times. A portion of the heating element located in a region close to a position opposing the shared liquid flow path is narrower than a portion of the heating element located at a position other than the region.
