Abstract: The present invention provides a conductive composition and a conductive paste from which a conductive film having a high conductivity and a low thermal expansion coefficient can be formed. The thermal expansion coefficient of an island fixing type conductive layer 10 is compatible with that of a substrate 12. A cracking of the island fixing type conductive layer 10 or a crack in the substrate 12 due to a difference between these thermal expansion coefficients is suitably inhibited. The thermal expansion coefficient of the island fixing type conductive layer 10 is adjusted by ZWP contained in the range from 10 to 55 (wt %) as a low-expansion filler. Thus, compared with the case where other low-expansion filler is added, the conductivity degradation is inhibited. Accordingly, the island fixing type conductive layer 10 having a high conductivity and a high bonding strength is obtained.

Abstract: Nickel paste contains nickel powder, a resin binder and an organic solvent, wherein the nickel powder is a small amount sulfur nickel powder including less than 100 ppm sulfur. This provides the nickel paste that the change in viscosity due to sulfur included in the paste can be preferably restrained by using nickel powder including extremely small amount of sulfur. Limitation of sulfur to the extremely small amount causes superior stability, and then, since kinds of solvents and resin binders are not limited, the change in viscosity can be preferably restrained with using the solvent that is hard to cause the chemical attack on the green sheet as described above. Thus, nickel paste that is hard to cause the chemical attack and the change in viscosity can be provided.
