Silver powder, method for producing same, and conductive resin composition

A silver powder comprising silver particles including dendrite silver particles, each of the dendrite silver particles being in a dendrite shape having only a single trunk and a plurality of branches branching from the single trunk,

• wherein a thickness of the single trunk is from 10 to 280 nm, and a length of the single trunk is from 0.5 to 10.0 μm,
• the number of the plurality of branches per length of the single trunk is from 6 to 30 branches/μm,
• the plurality of branches directly branch from the single trunk, and
• the percentage by number of the dendrite silver particles in the whole of the silver particles is 50 N % or more,
• the silver powder has a shrinkage rate of 0.3% or more, and the shrinkage rate is defined under the following conditions:
• 0.5 g of the silver powder is placed in a measurement fitting, to which a first load is applied, to obtain a sample;
• the sample is disposed on a thermo-mechanical analyzer, and a temperature of the sample is increased under a second load from 25° C. to 800° C. at a rate of 10° C./min in a mixed atmosphere of nitrogen and hydrogen;
• and
• an absolute value of a negative coefficient of expansion at 150° C. is defined as the shrinkage rate, and
• the silver powder has a crystallite size of from 10 to 49 nm.
