Abstract
A liquid ejecting head includes: a nozzle; a flow path member in which a flow path communicating with the nozzle is formed and which has an inner wall surface defining the flow path and an outer wall surface that faces away from the flow path with respect to the inner wall surface; and a temperature sensor disposed on a part of the outer wall surface and configured to detect a temperature of the liquid in the flow path. The flow path includes a narrowed region having a narrow width in a second direction orthogonal to a first direction in a direction in which the flow path extends, and the temperature sensor is disposed on a portion of the outer wall surface that forms the narrowed region.
