PROBLEM TO BE SOLVED: To provide an anchor instrument and an anchor member used for the anchor instrument surely preventing the anchor member from falling off a screw shaft. SOLUTION: The anchor member 30 mounted to a nut 20 screwed with the screw shaft 10, and insertable through an insertion hole 110 formed in a board 100, includes a nut holding part 33 holding the nut 20 and rotated around an axis of the screw shaft 10 integrally with the nut 20, and a board abutting part 34 extended from the nut holding part 33 and abutting on the other face of the board 100 when the anchor member 30 is inserted through the insertion hole 110 and moved from one face side to the other face side of the board 100. A guide part allowing the relative rotation of the screw shaft 10 and anchor member 30 between an inserting attitude and an abutting attitude in the state of holding the nut 20 in the nut holding part 33 is formed from the nut holding part 33 to the board abutting part 34.
