Provided is a syringe with which it is possible to hold with greater stability a liquid inside the barrel while maintaining the slidability and air-tightness between the barrel and the gasket without requiring fixation of silicone oil, and which is excellent in terms of accuracy of visual inspection. The syringe has a resin barrel, a gasket slidably inserted inside the barrel, a plunger attached to the gasket, and a silicone film obtained by applying silicone oil having a kinematic viscosity of 500 to 10,000 cSt over the inner peripheral surface of the barrel in an amount of 5 to 50 µg per 1 cm 2 of area.
