A surgical instrument management system includes a reader that reads an identification mark, and a management terminal that manages predetermined information associated with the identification mark, the predetermined information including a state of use of a surgical instrument. The management terminal includes a storage that stores the predetermined information and a predetermined discard condition under which the surgical instrument is to be discarded, an updater that updates the state of use of the surgical instrument, a first determiner that determines whether or not the state of use of the surgical instrument meets the discard condition, and a first notifier that, in the case where the first determiner determines that the state of use of the surgical instrument meets the discard condition, notifies that the surgical instrument needs to be discarded.
