PROBLEM TO BE SOLVED: To provide a conductive compound which enables high joining strength at a joining interface and enables high electric reliability at the joining interface even under severe environmental conditions such as temperature changes or vibrations. SOLUTION: The conductive compound comprises metal powder which consists of silver particles whose diameters are 0.5 to 60μm and tin particles whose diameters are 0.5 to 60μm, and dispersion medium wherein the tin particles have ball shapes. The metal powder of 85 to 93 wt.% is contained in the electrically conductive compound, the silver particles and the tin particles are mixed in the wt. radio of 75 to 50:25 to 50, and single or mixed solvent having boiling temperature of 200°C or more is chosen from polyhydric alcohol, hydrocarbon or alcohol ester as the dispersion medium.
