PROBLEM TO BE SOLVED: To produce efficiently, in a large quantity, by using a usual ready mixed concrete having fluidity, a concrete block the part of which is provided with countless voids and the strength as the whole of which is improved. SOLUTION: The concrete block is the one in which porous molded bodies 1 having innumerable voids are embedded in a concrete-made block main body 2 in the state that part of their surfaces are exposed to the outside. Further, the concrete block is arranged with flexible sheets 3 in the boundaries between the porous molded bodies 1 and the block main body 2 which can be deformed to invade into the voids of the porous molded bodies 1 with being pressed by the block main body 2.
