According to one embodiment, a nozzle head includes a main body having a space in an interior of the main body, the space being capable of storing a source material liquid, a first nozzle provided at the main body, the first nozzle ejecting the source material liquid stored in the main body, and a second nozzle provided at the main body, the second nozzle supplying a cleaning liquid to a vicinity of an outlet of the first nozzle.
First claim
Opening claim text (preview).
What is claimed is: 1. A nozzle head, comprising: a main body having an interior space capable of storing a source material liquid; a first nozzle provided at the main body configured to eject the source material liquid stored in the interior space, the first nozzle comprising a first tip wherefrom the source material liquid is ejected; a second nozzle provided at the main body configured to supply a cleaning liquid while the first nozzle is not ejecting the source material liquid, the second nozzle comprising a hole with a second tip wherefrom the cleaning liquid is supplied; and a driver configured to move the main body between first and second positions, said first position being where the source material liquid is ejected from the first nozzle and said second position being where the cleaning liquid is supplied from the second nozzle, wherein, the first nozzle is provided inside the hole of the second nozzle such that the first tip protrudes from the second tip, and a protrusion amount of the first tip from the second tip is set to be not less than 1 mm and not more than 20 mm. 2.
