PURPOSE: A nozzle tip for maintaining the dropping amount of droplets preset by a user is provided to maintain the structure of a flow passage inside the nozzle tip after decreasing the cross section area on the tip-end of the nozzle tip. CONSTITUTION: A nozzle tip for maintaining the dropping amount of droplets preset by a user comprises the following: a large diameter unit(321) having the predetermined external diameter; a small diameter unit having the external diameter smaller than the large diameter unit; a flow passage passing through the large and small diameter units, and having a tapering structure narrowing toward the direction of an outlet from an inlet; and a liquid crystal diffusion preventing member(330) dispersing liquid crystal to the outer circumference of the small diameter unit, and having a cylindrical tube shape. The liquid crystal diffusion preventing member is Teflon. The nozzle tip is produced with ceramics.
