A sealing composition which can be handled in a semi-cured state and can obtain a sintered body having excellent joining strength and sealing performance is provided. A sealing composition including a solder powder, coated silver particles including silver core particles and a coating agent arranged on a surface of the silver core particles, and a solvent is provided. Further, a sintering temperature (T2) of the coated silver particles and a boiling point (T3) of the solvent satisfy T2≤T3.
