PROBLEM TO BE SOLVED: To provide a method for producing a sheet-like molded body by rotating and transferring sheet members which achieves rotation and transfer processing, the method having high degree of freedom without using a complicated mechanism.SOLUTION: The method for producing a sheet-like molded body comprises: a sheet member cutting step, in which a set of four pieces of sheet members on the front, back, right and left sides in an initial arrangement are cut out from a sheet master roll in a substantially continuous fashion in the longitudinal direction so that the sheet members are axially symmetric in the transverse direction and have identical shapes in the longitudinal direction and a rotation and transfer step, in which the set of sheet members are held by a transfer means and are rotated axially so as to place two diagonal pieces of the members at right and left positions deviated in the transfer direction, and to further rotate by the transfer means the two members located diagonally to be placed respectively on the right and left of the already placed two sheet members.
