PROBLEM TO BE SOLVED: To provide a sealing material capable of suppressing the change of a crystallization temperature, and a sealed body.SOLUTION: Provided is a sealing material including crystalline bismuth-based glass powder. The glass composition of the bismuth-based glass powder includes, by mol% expression, BiOby 25 to 40.5%, BOby 15 to 40% and ZnO by 20 to 45%, and in which the total of the SiOand the AlOis 0.3 to 10%, and a value obtained by dividing the molar quantity of the ZnO with the molar quantity of the BiOis 0.7 or higher. |
