A composition exhibits excellent heat resistance and mounting reliability when bonding a semiconductor power element to a metal lead frame, which is also free of lead and thereby places little burden on the environment. An electrically conductive composition contains at least a sulfide compound represented by RSR (wherein R is an organic group containing at least carbon; R is an organic group that is the same as or different from R; and R and R may be bonded to each other to form a so-called cyclic sulfide) and metal particles containing at least Cu, Sn or Ni as its essential component. Further, a conductive paste and a conductive bonding film each are produced using the electrically conductive composition. A dicing die bonding film is obtained by bonding the conductive bonding film with an adhesive tape.

Bonded surfaces are formed by adhering first nanorods and second nanorods to respective first and second surfaces. The first shell is formed on the first nanorods and the second shell is formed on the second nanorods, wherein at least one of the first nanorods and second nanorods, and the first shell and the second shell are formed of distinct metals. The surfaces are then exposed to at least one condition that causes the distinct metals to form an alloy, such as eutectic alloy having a melting point below the temperature at which the alloy is formed, thereby bonding the surfaces upon which solidification of the alloy.
