Abstract
In a syringe, which is a prefilled syringe, when a cap body is attached to a cylindrical portion, a first sealing section is compressed radially inward by an inner peripheral surface constituting an opening of the cylindrical portion, thereby sealing a distal end section of a flow path in a liquid-tight manner, and a second sealing section is compressed radially inward by an inner peripheral surface of a proximal end section of the cylindrical portion, thereby sealing a proximal end section of the flow path in a liquid-tight manner.
