1. A pipette tip comprising:
- a tubular body having a distal end portion in which an ejection opening that ejects liquid from an injector is formed; and
a projection that is provided on the distal end portion and that projects from a region around the ejection opening in an ejection direction of the liquid, the projection being partially disposed around an axis of the body.

Abstract
A pipette tip includes a body and projections. In the body, a flow passage in which liquid from the syringe flows and an ejection opening that ejects the liquid, which has flowed through the flow passage, to the outside are formed. The ejection opening is formed in a distal end portion. The projections are provided on the distal end portion and protrude from a region around the ejection opening in the ejection direction of liquid. The projections are partially disposed around the central axis of the body. Even in a case where a residual droplet adheres to the ejection opening, the residual droplet does not adhere to an injection opening of a sample container, because the projections guard a region around the residual droplet.
