Abstract

To provide a port member that is attached to a container for storing liquid and that can ensure sealing and opening property as well as ensuring insertion property of other member, and a liquid storage container and a liquid-filled container for living body administration.SOLUTION: A port member 30 includes a cylindrical base part 31, a cylindrical port body part 32 protruded in the distal direction from the base part 31, a closing part 33 extending in the distal direction from the port body part 32, and an annular concave part 35 provided between the port body part 32 and the closing part 33 and forming an annular thin wall part 34 for breaking. The port body part 32 has an annular inner peripheral surface corner part 36 formed on the inner peripheral surface. The annular concave part 35 has an annular inner edge corner part 37. The annular inner peripheral corner part 36 is provided at a position close to the annular inner edge corner part 37 and closer to the base part 31 than the annular inner edge corner part 37.SELECTED DRAWING: Figure 4
