Board for manufacturing concrete product

The present invention relates to a board for manufacturing a concrete product and, more particularly, to a board for manufacturing a concrete product, which is used for manufacturing a concrete product such as a concrete block and a paving stone and includes upper and lower plates and a side surface support frame connecting the upper and lower plates, which are separately configured, thereby making it unnecessary to manufacture a mold for each size and reinforcing a portion to which a force is applied when the concrete product is manufactured as well as reducing the weight thereof while maintaining the rigidity thereof. Thus, the present invention can reduce costs for manufacturing a board and reduce noise generated when the concrete product is manufactured.
