Abstract: A bonding material includes a solder alloy having a median diameter D50 of 100 nm to 2000 nm, made from Sn, Bi, In, and other unavoidable components, and having a melting point of less than or equal to 100° C., metal nanoparticles that are Cu nanoparticles having a median diameter D50 of 50 nm to 500 nm, and a flux, wherein the metal nanoparticles include a protective film on a surface of the metal nanoparticles, the protective film separating at a temperature higher than a melting point of the solder alloy and lower than 100° C., and a weight ratio between the solder alloy and the metal nanoparticles is a ratio at which all Sn and In contained in the solder alloy become intermetallic compounds with the metal nanoparticles in an equilibrium state diagram.

Abstract: To provide a solder material capable of performing soldering with high reliability while suppressing materials other than a solder metal to remain inside the solder after the soldering. Coil-shaped carbons are heated by electromagnetic waves by using a solder material in which coil-shaped carbons of 0.5 weight % to 1.5 weight % with respect to a weight of a solder paste are mixed, thereby performing soldering by heating the solder material itself.
