A syringe needle disposal container for disposing of a syringe needle having a needle holder detachably screw-fitted to an end of a syringe body and a needle body, which includes a lid that covers an opening of a container body and a moving member mounted on the lid so as to be slide-movable. A first holding part for holding one side of needle holder is provided at a predetermined part of the lid. The moving member is formed with a second holding part for holding the other side of the needle holder. An open end of the first holding part on the lid side is deviated toward the first holding part with respect to a reference center axis line L that passes through the center P of a syringe needle holding part in the holding position state and that is substantially perpendicular to a slide-moving direction of the moving member.
