1. A composite structure manufacturing method comprising: a lamination step of forming a laminate having a plate shape by laminating a plurality of fiber reinforcing resin sheets; a pressing deformation step of forming a recessed portion or a projecting portion in a predetermined portion of the laminate by pressing a plate surface of the laminate with a rotating body that rolls along the plate surface of the laminate; a lateral deformation step of providing a predetermined shape to a cross section of the laminate in a longitudinal direction by deforming the laminate in a lateral direction after the pressing deformation step; and a longitudinal deformation step of providing a predetermined shape to a cross section of the laminate in the lateral direction by deforming the laminate in the longitudinal direction after the pressing deformation step.
