Claim 10:
11. A liquid ejecting head comprising
a nozzle configured to eject a liquid;
a flow path member in which a flow path that is configured to communicate the liquid to 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,
wherein 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,
the temperature sensor is disposed on a portion of the outer wall surface that forms the narrowed region,
the flow path member includes a protrusion portion defining a part of the inner wall surface that faces a part of the inner surface that faces away from the temperature sensor and protruding toward the temperature sensor,
the protrusion portion includes a first slope disposed upstream of the temperature sensor in the first direction, and
a second position of the first slope positioned downstream of a first position of the first slope is closer to the temperature sensor than is the first position with respect to the second direction.
