There is disclosed a liquid medicine continuous infuser having a basic structure comprising a bag-shaped member that can apply a pressure to a liquid medicine accommodated inside the infuser, an inflow/outflow section for flowing in and flowing out the liquid medicine, and an area positioned inside the bag-shaped member and having a predetermined volume. The above pressure provides a predetermined characteristic curve in relation to the capacity of the bag-shaped member, and the area having the predetermined volume is for increasing the capacity of the bag-shaped member when the liquid medicine is accommodated inside the bag-shaped member. Further, the bag-shaped member is for applying a pressure to a liquid medicine accommodated inside the bag-shaped member along with the predetermined characteristic curve, with a pressure corresponding to the capacity increased by the area having the predetermined volume, when the liquid medicine is accommodated inside the bag-shaped member used, as an initial value.
