Abstract: A method for molding a composite material includes a conductive wire-shaped material arrangement step and a magnetic field application step. The conductive wire-shaped material arrangement step is a step for arranging, in a pre-reaction composite material including reinforcing fibers, a plurality of conductive wire-shaped materials along a direction intersecting the reinforcing fibers with intervals wider than intervals of the reinforcing fibers in a plane on which the reinforcing fibers are arranged. The magnetic field application step is a step for applying a magnetic field in a direction intersecting the plane on which the reinforcing fibers are arranged.
