PROBLEM TO BE SOLVED: To provide a concrete top end indicator easy in installation to a stud material even after bar arrangement, causing no looseness and slipping-out by external force such as a collision of a concrete hose, allowing firm installation, and accurately displaying the concrete top end. SOLUTION: This concrete top end indicator is composed of a support piece for abutting to an anchor part of the stud material suspended by a beam member, a support shaft for vertically advancing-retreating to a female screw part arranged in the support piece and a top end display part for vertically advancing-retreating to the support shaft, and is fixed in a state of being stretched between the beam member and the anchor part of the stud material.
