Abstract
A liquid ejecting head includes: a first flow path member that defines a part of a flow path communicating with a plurality of nozzles; a second flow path member that defines a part of the flow path; a first bonding portion that liquid-tightly couples a part of the flow path of the first flow path member and a part of the flow path of the second flow path member; and a second bonding portion that is a bonding portion defining an inner wall of the flow path, the second bonding portion defining a detection space that serves as a space for detecting a degree of deterioration of the first bonding portion and that is partitioned from the flow path.
