Abstract (en)

Particles for joining material are such that an organic protective film is formed on the surface of copper nanoparticles, and have a BET specific surface area in a range of 3.5 m<sup>2</sup>/g to 8 m<sup>2</sup>/g, and a BET diameter in a range of 80 nm to 200 nm, wherein the organic protective film is included in a range of 0.5% to 2.0% by mass with respect to the particles for joining material. When the particles for joining material are analyzed by using the Time-Of-Flight Secondary Ion Mass Spectrometry (TOF-SIMS) method, respective detected amounts of C<sub>3</sub>H<sub>4</sub>O<sub>2</sub><sup>-</sup> ions and C<sub>3</sub>H<sub>4</sub>O<sub>2</sub><sup>-</sup> ions are in a range of 0.05 times to 0.2 times a detected amount of Cu<sup>+</sup> ions, and a detected amount of ions of C<sub>5</sub> or more is in a range less than 0.005 times the detected amount of Cu<sup>+</sup> ions.
