PROBLEM TO BE SOLVED: To provide a liquid delivery head which can obtain good refilling characteristics in the liquid delivery head with a heating element positioned under a condition that it is floated from the inner wall face of a flow path in the flow path to improve energy conversion efficiency. SOLUTION: The heating element is supported under the condition that it is floated from the inner wall face of the flow path so as not to close the flow path, and the heating face of the heating element is arranged so that it is in parallel to the flow direction of the liquid in the flow path.
