Abstract
A liquid ejecting head includes a flow path member in which a first substrate and a second substrate are joined to each other by an adhesive so that flow paths extending in directions along a junction surface between the first substrate and the second substrate are formed, and an ejection unit. The flow paths include a first flow path through which a first liquid flows and a second flow path through which a second liquid flows. The ratio of presence of a flow path between a demarcation wall that at least partially forms the first flow path and an external contour of the flow path member in the directions along the junction surfaces is greater than the ratio of presence of a flow path between a demarcation wall that at least partially forms the second flow path and the external contour of the flow path member.
