1. A discharge member with a closing member comprising:
a discharge member used for discharging contents accommodated in a container; and
a closing member, wherein
the discharge member includes a tubular part formed into a tubular shape, through which the contents from the container pass, provided with an annular end surface around an opening formed at one end portion of the tubular part in an axial direction, the tubular part including a functional resin layer disposed as an intermediate layer; and
the closing member includes an annular contact part coming into contact with the annular end surface to close the opening positioned at the one end portion of the tubular part, and
when positions in a radial direction of the tubular part are compared, a contact point where the annular contact part comes into contact with the annular end surface is positioned closer to an axial center of the tubular part than the functional resin layer.
