Abstract
A liquid medicine reservoir that supplies liquid medicine to a liquid-medicine discharging portion via a communicating portion includes a cylindrical body configured to hold the liquid medicine therein, a first sealing portion to which the communicating portion is connected, the first sealing portion sealing the cylindrical body, and a second sealing portion configured to seal an end of the cylindrical body opposite the first sealing portion. At least one of the first sealing portion and the second sealing portion move relative to each other in accordance with the amount of liquid medicine. A substance configured to inhibit discharging of the liquid medicine is stored in a space in the cylindrical body that is on an inner side of the second sealing portion and that is separate from the liquid medicine.
