Abstract
A liquid ejecting head includes a first case that houses a flow path member that is provided with a liquid flow path, a second case that includes a head unit, a seal member that includes a connecting portion that seals and liquid-tightly connects the liquid flow path on a first case side and a liquid flow path on a second case side. The liquid ejecting head ejects a liquid supplied from the flow path member from a nozzle of the head unit. A flow path-isolating member having higher gas barrier property than the seal member is disposed between the first case and the seal member. The flow path member is disposed in a sealed space that is defined in the first case by a flow path-isolating member being joined to the first case.
