PROBLEM TO BE SOLVED: To provide a droplet discharge head which is excellent in a discharge characteristic through further reduction of dead zones by controlling air bubbles, and thereby forms a high quality image. SOLUTION: The droplet discharge head is provided with a droplet discharge section 1 for discharging a droplet, a liquid chamber 2 which communicates with the droplet discharge outlet 11 of the droplet discharge section 1 and makes thermal energy act on a liquid, a liquid supply port 3 for supplying the liquid to the liquid chamber 2, a heat resistor 4 for producing the thermal energy in the liquid chamber 2, a partition wall 5 for forming the liquid chamber 2, a curve 6 having such a shape that an angle Z between a tangent line 50 facing the liquid chamber 2 of the partition wall 5 and the heat resistor 4 keeps on increasing up to 90°as it is separated from the heat resistor, and then is continuously decreased.
