To provide the filling and molding method of a concrete secondary product, by which a green concrete can be filled uniformly and the external appearance and properties of a product is remarkably improved.

By giving either one motion among a rocking motion (this motion is executed singly to either the longitudinal direction of a form or its widthwise direction or simultaneously to both its above-mentioned directions or alternately to one direction between its above-mentioned direction), sliding motion (this motion is executed singly to either the longitudinal direction of the form or its widthwise direction or simultaneously to both its above- mentioned direction or alternately to one direction between its above-mentioned directions), and a twisting motion or a mixed motion of these two or three motions in a large stroke and, at the same time, with a long period, a ready mixed concrete is filled in a molding form to be molded.
