PROBLEM TO BE SOLVED: To provide a spacer for reinforced concrete allowing manufacturing of a reinforced concrete product of fine finish, reducing a block face exposed to the surface of the product. SOLUTION: This spacer 1 for holding a specified space between a reinforcement 51 and a form 6 or a floor in forming reinforced concrete, comprises a concrete block 2 having at least three bulge parts 4 with the tips 41 on the same circumference, and disposed in the state of the tips 41 abutting on the form 6 or the floor; and a locking fitting 3 with a base part fixed to the rear end face of the block 2. It is preferable to have four bulge parts 4 formed in semispherical shape with the tips 41 on the same circumference from the viewpoint of stability in installing the reinforcement 51 at the form 6 and filling performance of ready-mixed concrete between the bulge parts 4.
