Abstract
Selected is a composition containing a silver powder generating gaseous carbon dioxide, acetone vapor, and water vapor in a case where the silver powder is heated at 100° C., a stress relaxation body having a Young's modulus lower than a Young's modulus of a sintered body of the silver powder, and a solvent, in which a particle size distribution of primary particles of the silver powder has a first peak in a range of a particle size of 20 to 70 nm and a second peak in a range of a particle size of 200 to 500 nm, an organic substance in the silver powder is decomposed by 50% by mass or more at 150° C., and a mass ratio between the silver powder and the stress relaxation body is 99:1 to 60:40.
Claims5
A composition comprising:
- a silver powder generating gaseous carbon dioxide, acetone vapor, and water vapor in a case where the silver powder is heated at 100° C.;
- a stress relaxation body having a Young's modulus lower than a Young's modulus of a sintered body of the silver powder;
- and
