PROBLEM TO BE SOLVED: To provide a liquid droplet jetting apparatus equipped with a protecting structure which surely protects a jet orifice surrounding region of a liquid droplet jetting surface and is resistant to drop from the liquid droplet jetting surface, and to provide its manufacturing method. SOLUTION: An inkjet head has the liquid droplet jetting surface 3a where a jet orifice 54a of a nozzle 54 to jet liquid droplets is arranged. A filling hole 66 is formed at a position near the jet orifice 54a of the liquid droplet jetting surface 3a, which is open to the liquid droplet jetting surface 3a and is larger in diameter at a deep part from the liquid droplet jetting surface 3a than at an opening part. A fluid material is filled in the filling hole 66 and solidified in a state while partly projecting from the opening part of the filling hole 66, whereby a projection 65 projecting from the liquid droplet jetting surface 3a is formed.
