  • Conductive composition and conductive paste
    Patent number: 7740773
    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.
