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.

A pressure head is provided facing a magnetic field coil via the composite material. The magnetic field coil is provided on one side of the composite material, and the pressure head is provided on another side of the composite material.
