Zusammenfassung:A calcined solid drawing material capable of drawing a line excellent in color development and transparent while having a high strength regardless of a black core or a colored core. The calcined solid drawing material is provided with a skeleton core constituted by at least an extender and a binder component, and a drawn line permeability T of the drawn line calculated by the following equation (I) is 0.8 or more: T=L*w−L*b/L*b−L*pL*w: brightness of a drawn line written on white paperL*b: brightness of a drawn line written on a black paperL∗p: brightness of the black paper.
