PROBLEM TO BE SOLVED: To provide a form for producing a block without requiring attaching/detaching work of a core, capable of shortening a production time, and also capable of reducing space required to producing the block and accessary equipment. SOLUTION: The core is divided into three parts in a longitudinal direction to form a central core 6, a front side core 7 and a back side core 8. The central core 6 is connected to an impression core 1d having length not less than its maximum length, the front side core 7 is connected to a front end plate 4, and the back side core 8 is connected to a back end plate 5. Therefore, concrete can be placed in the concrete form in a state where lateral side plates 2 and 3 are closed, also longitudinal end plates 4 and 5 are closed, and the front side core 7 and the back side core 8 are integrated with the central core 6. Further a side groove block CC can be brought out from the concrete form in a state where the lateral side plates 2 and 3 are opened, also the longitudinal end plates 4 and 5 are opened, and the front side core 7 and the back side core 8 are separated from the central core 6 to be pulled out from the side groove block CC.
