Provided are a silver element containing silver acetonedicarboxylate with high silver content, and capable of providing a silver element with excellent electrical conductivity, flatness, and adhesivity through heating even for a short time at a low temperature of below the decomposition temperature of the silver salt, and having excellent storage stability, as well as a substrate having a silver element formed thereon with the composition. The composition is characterized by a particular ratio of silver compound (A) represented by formula (1) and amine compound (B) represented by formula (2): (R: H, &#x2014;(CY)a-CH, &#x2014;((CH)b-O&#x2014;CHZ)c-CH; R: &#x2014;(CY)d-CH, &#x2014;((CH)e-O&#x2014;CHZ)f-CH, Y: H, &#x2014;(CH)g-CH; Z: H, &#x2014;(CH)h-CH; a: 0-8; b: 1-4; c: 1-3; d: 1-8; e: 1-4; f: 1-3; g: 1-3; h: 1-2).
