PROBLEM TO BE SOLVED: To provide, when laying reinforcement bars in placing concrete, a support for an intersection of reinforcement bars, wherein a support having resiliency without requiring a wire for bundling is used, so that it is easy for a worker, a trouble in arranging reinforcements can be avoided without generating a clearance when placing concrete, costs can be saved, a work period can be shortened and the field work can be streamlined. SOLUTION: The support for intersection of reinforcement bars, which resiliently and reliably fixes crossing reinforcement bars 1b, is composed as follows. A cylindrical resilient body 1 of a designated thickness t stands while an elongate hole 2-1 having a width d2 of approximately same dimension as the diameterϕof the reinforcement bar for detachably engaging a reinforcement bar Ib is cut upward in a side face 3-1 as well as in the opposing side face 1-4 of the lower half of the cylindrical resilient body 1. Another elongate hole 2-2 is cut downward in a side face 1-1 as well as in the opposing side face 1-2 of the upper half so that one reinforcement bar Ib bisects the other reinforcement bar Ib at right angles and that the crossing two reinforcement bars Ib, Ib can be retained at the predetermined position and the predetermined height.
