PROBLEM TO BE SOLVED: To provide a concrete form suitable for reducing the deburring work of a concrete product and shortening the work time required in the production of the concrete product. SOLUTION: In the concrete form for manufacturing a cylindrical concrete product by casting concrete C in the space between an outer form 1 and an inner form 2 to solidify the same, the inner form 2 has a one-part structure formed by integrally joining an elastic member 3 capable of drawing the inner form 2 inside and a panel member 5 having rigidity higher than that of the elastic member 3.
