ABSTRACT:
An apparatus for ejecting droplets is provided with a ejecting head for discharging droplets, an electric circuit board having an electric circuit formed on a surface of the electric circuit board, the electric circuit being connected to the ejecting head, a holder for supporting the ejecting head and the electric circuit board, and a cover that overlaps the surface of the electric circuit board when the cover is fixed to the holder. The apparatus for ejecting droplets is further provided with a seal member that fills a gap formed between a peripheral region of the surface of the electric circuit board and an inner surface of the cover. The seal member effectively prevents droplets mist from penetrating to the electric circuit.
