PROBLEM TO BE SOLVED: To provide a spacer joining body which enables facilitation of transport and a reduction in transport cost, and which enables easy and accurate discrimination between heights of reinforcing-bar supporting surfaces of spacers. SOLUTION: This spacer joining body; which is wholly molded integrally of concrete, is constituted by joining the plural spacers 5 via joining parts 6 in one direction. The spacer 5 is provided with the two supporting surfaces 3a and 3b capable of supporting a reinforcing bar at different heights. A joining- side surface 10 of the spacer 5 is formed in a rectangular shape, and the reinforcing bar is supported by the supporting surface 3b on a long side 12 and the supporting surface 3a on a short side. The joining part 6 is formed between groove bottoms of recessed grooves 7 and 7 which are provided at the same depth in such a manner as to be brought into an opposed state on right and left sides of a boundary part between the adjacent spacers 5. Additionally, the joining part 6 is formed so as to have such a clearly rectangular cross section as to be longer in a lengthwise direction of the long side 12 of the spacer 5. Destruction of the joining part 6 can make each of the spacers 5 independent.
