A medicine syringe has a syringe barrel, piston and plunger rod. The syringe barrel is provided with a cylindrical main body defining therein a chamber to be filled with a medical solution, and an injection nozzle portion formed at an end portion of the main body and defining therein a hollow bore in communication with the chamber. The chamber and hollow bore have a total capacity of not greater than 0.5 mL. The chamber and hollow bore are formed such that the piston is slidable in a range of from 20 to 100 mm and is allowed to slide liquid-tight into the hollow bore beyond the chamber.
