PURPOSE: To stably perform the coating of a film material with uniform quantity by forming an inner wall part so that discharge path along the axis direction may be fixed in a discharge part for discharging a film material from a housing part to a body to be coated and forming the outer wall and the axis of the discharge part at an acute angles.

CONSTITUTION: A coating device X is constituted of a housing 7 for housing a film material A, a discharge pipe 8 for discharging the film material A housed in the housing 7, and a dispenser 9 for discharging the film material A from the lower end of the discharge pipe 8. The dispenser 9 converts the pressure of air flowing out from a compressor 10 to a specific one end causes the air to flow into cylinder 7 through an air pipe 11. In such constitution, the discharge pipe 8 forms an inner wall part so as to fix a discharge path along the axis direction. And in the discharge pipe 8, an angle D between the axis and the outer wall in the discharge port having specific inner diameter E and length L is made an acute one. Further, in the discharge pipe 8, at least the discharge port is formed of fluororesin.
