To develop a manufacturing method of a centrifugally molded concrete product constituted so as to easily manufacture a concrete product having a single-layer or multi-layer structure by centrifugal molding, and a manufacturing apparatus therefor.

A supply device 30 concentrically rotated almost in synchronous relation to a centrifugal matrix 10 is provided in the centrifugal matrix 10 and concrete is charged in inner forms 11 while controlling the rotational speed of a supply port 32 and the supply quantity of concrete so as to match them with the arrangement of the inner forms 11 to manufacture the centrifugally molded concrete product. In this case, concretes different in kind are charged in the inner forms 11 in series to manufacture the concrete product having a multi-layer structure.
