Abstract: An access port can be connected to a catheter and includes a port body including a liquid storage portion and a diaphragm body covering the liquid storage portion. The port body includes a connection passage connected to the liquid storage portion and allows the liquid storage portion to communicate with the inside of the catheter. In the cross-section along the axial direction of the connection passage at the connection position where the connection passage is connected to the liquid storage portion, the length in the direction perpendicular to the axial direction between the surface of the diaphragm body on the side opposite to the liquid storage portion and the inner surface of the liquid storage portion gradually decreases as it proceeds away from the connection position in the inclined region exceeding half of the liquid storage portion along the axial direction.
