Abstract
Provided is a liquid ejecting head which includes a head main body which has liquid ejection surface through which liquid is ejected, a flexible wiring substrate which is connected to the head main body, and a flow-path member having flow path through which liquid is supplied to the head main body. The flow-path member has an opening portion through which the substrate is inserted. The substrate extends to the flow-path member, with respect to the head main body. The substrate is inclined in a direction directed toward a first surface side of both surfaces of the substrate. In an area on a second surface side of both surfaces of the substrate, the flow path has a portion extending along the head main body.
