Provided is an artificial-blood-vessel connector which includes: a connector portion (200) which includes a first cylindrical body portion (210) where a male threaded portion (211) and a flat surface portion (212) where the male threaded portion is not formed are alternately formed along a circumferential direction of an outer peripheral surface, and a second cylindrical body portion (220) which is configured to be fitted into the inside of an artificial blood vessel (20) a ferrule (300) which includes a cylindrical portion (310) which is configured to be fitted on an outer peripheral surface of the second cylindrical body portion (220) by way of the artificial blood vessel (20) by being made to slide linearly on a surface of the artificial blood vessel (20), and a pawl plate portion (320) which is brought into contact with a flat surface portion (212) of the first cylindrical body portion (210) and a nut (400) which includes a female threaded portion and is configured to be connected to the connector portion (200) by making the female threaded portion threadedly engage with the male threaded portion (211) of the first cylindrical body portion (210) in a state where the nut (400) covers the ferrule (300). With such a configuration, it is possible to prevent occurrence of a damage on the artificial blood vessel and, at the same time, it is possible to increase reliability in connection between the artificial blood vessel and the artificial-blood-vessel connector.
