PROBLEM TO BE SOLVED: To ensure an anti-corrosive measure for an anchor by securing the cover of a bundle of a plurality of tension members and a plurality of deformed bars so as to prevent the bundle from being biased with respect to a diameter of a hole, in terms of a spacer for the anchor. SOLUTION: In the tubular spacer 10, a space part for inserting a bundle of strands is provided in a central part. In the spacer 1 for the anchor, flexible protrusive plates 10b like a flat plate along the longitudinal direction of the strand are provided on the outer peripheral part of the space part 10a at proper intervals in the circumferential direction of the outer peripheral part, and the height of the protrusive plate from a surface 10c of the outer peripheral part is set to be a height which secures the cover (a) of a reinforcing bar housed in the circumferential space part between the adjacent protrusive plates.
