Abstract (en)
The composite copper particle of the invention is a composite copper particle including a flake-like copper particle and a plurality of inorganic oxide particles which are finer than the flake-like copper particle. The inorganic oxide particles are unevenly distributed on a surface of the flake-like copper particle. The composite copper particle preferably has a volume cumulative particle diameter D 50 at a cumulative volume of 50 vol% as measured by a laser diffraction scattering method of 0.1 µm to 10 µm. An aspect ratio of the maximum diameter d of a plane of the composite copper particle to the maximum thickness t of the composite copper particle, d/t, is preferably 5 to 30. The inorganic oxide particles preferably have a higher hardness than copper.
