1. A port-equipped bag comprising:
a bag body that is formed in a bag shape with a sheet and has an accommodation portion therein; and
a cylindrical port member that is attached to the bag body and has one end communicating with the accommodation portion and the other end at which an opening exposed outside the bag is formed,
wherein an inner plug and a cap for pressing the inner plug are attachable to the port member,
the port member includes an attaching target portion that is covered by the cap in a case in which the cap is attached to the port member and an annular lip that is formed at a peripheral edge of the opening and protrudes outward from the port member,
the lip has an annular engagement surface facing the bag body, and
the engagement surface has an angle of 45° to less than 90° with respect to an outer peripheral surface of the attaching target portion in a cross section in an axial direction of the attaching target portion and the engagement surface is in an overhung state
a tensile elastic modulus of the sheet is 550 MPa to 1500 MPa,
a thickness of the sheet is 250 μm to 400 μm,
a product (M×T) of the tensile elastic modulus M (MPa) and the sheet thickness T (μm) of the sheet is 137,500 or more and 300,000 or less,
the port member is formed of a synthetic resin having a bending elastic modulus of 140 MPa or more and 2000 MPa or less.
