Provided are: a silver-containing composition which contains silver acetonedicarboxylate having a high silver content, enables the production of a silver element having excellent electrical conductivity, flatness and adhesion properties even when the composition is heated at a low temperature that is lower than the decomposition temperatures of silver salts for a short time, and has high storage stability; and a base for use in the formation of a silver element, which is produced using the composition. The composition according to the present invention is characterized by comprising (A) a silver compound represented by formula (1) and (B) an amine compound represented by formula (2) at a specified content ratio. (R 1 : H, -(CY 2 )a-CH 3 , -((CH 2 )b-O-CHZ)c-CH 3 ; R 2 : -(CY 2 )d-CH 3 , -((CH 2 )e-O-CHZ)f-CH 3 ; Y: H, -(CH 2 )g-CH 3 ; Z: H, -(CH 2 )h-CH 3 ; a: 0 to 8; b: 1 to 4; c: 1 to 3; d: 1 to 8; e: 1 to 4; f: 1 to 3; g: 1 to 3; h: 1 to 2) |
