Abstract

The present invention provides: a puncture port which is capable of ensuring sealability when a puncture is formed, regardless of the size of an insertion part of a puncture instrument; and a liquid storage container equipped with such a puncture port. A puncture port 40 is provided to a liquid storage container for storing a liquid, is to be punctured by a puncture instrument 200 equipped with a needle tube part 210 having a through-hole 215 formed therein, and comprises: a cylindrical port body 43; and a first partition wall 411 and a second partition wall 421 that are provided to the port body 43. In the puncturing direction, the distance D between the first partition wall 411 and the second partition wall 421 is longer than the length HL in the puncturing direction of an opening portion 220 of the through-hole 215 at least at the leading end of the needle tube part 210.
