To provide a green sheet having a writing surface on which a high definition pattern can be written using liquid droplets of conductive ink without requiring extra surface treatment, and to provide a method of manufacturing the same.

When a kneaded matter becoming a green sheet 18 is produced by kneading glass ceramic powder and binder resin using a dispersion medium, hydrophilic receptive resin is additionally kneaded and a green sheet 18 produced by molding a kneaded matter is rendered hydrophilic and receptive. Since a liquid droplet Fb ejected from an ejection head 30 and impacting on the green sheet 18 adheres to the impact position on a writing surface 18a and then evaporates and dries up at the impact position, a fine liquid wiring pattern PL can be written on a writing surface 18a with metal ink F.
