The objective of the present invention is to retain the hot sealing properties of a shaped joint material while suppressing igniting or smoke generation from the combustible material in the shaped joint material. The shaped joint material is obtained by adding a ratio of 26-50% by mass of an organic material additive into 100% by mass of a mixture including 50-90% by mass of a gibbsite aluminum hydroxide raw material, 1-9% by mass of clay, 9-23% by mass of graphite, and the balance mostly other refractory raw material, and kneading, shaping, and drying the result. |
