A method for manufacturing a resin sheet includes a coating step; a heating step; and a pressurizing step. In the coating step, linear metal nanomaterial is coated on a surface of a resin film having thermal plasticity. In the heating step, the resin film having the linear metal nanomaterial coated on the surface thereof is heated and softened. In the pressurizing step, the resin film having the linear metal nanomaterial coated on the surface thereof is pressurized to press the linear metal nanomaterial along a direction orthogonal to the surface on which the linear metal nanomaterial is coated. Thus, the coated linear metal nanomaterial penetrates the resin film to obtain the resin sheet containing the linear metal nanomaterial.
