PROBLEM TO BE SOLVED: To provide a coater capable of delicately regulating a coating material discharge rate by delicately adjusting the pressing to a container body. SOLUTION: A container body 21 of the coater, which is formed by disposing a coating tip 2 capable of discharging and applying a coating material in front of the aperture of the container body 21 internally provided with a coating material housing chamber, is formed with longitudinal pleat-like bellows part 21b at least at one point on its flank. As a result, the pressure deformation quantity of the container body may be delicately adjusted from large to small by the flexibility of the container body.
