Abstract
Provided is a composite nanometal paste which, when a layer of the paste interposed between upper and lower bodies is sintered in an inert gas under no load until the layer turns to a metal layer, attains a shear bond strength between the upper and lower bodies of 10 MPa or higher. The composite nanometal paste contains, as metallic components, composite metallic nanoparticles comprising metal cores with an average particle diameter of X (nm) and an organic coating layer formed around the circumference, metallic nanofiller particles having an average particle diameter of d (nm), and metallic filler particles having an average particle diameter of D (nm), and satisfies the first relation X<d<D and the second relation X<d<100 (nm). Furthermore, this is a composite nanometal paste in which said average particle diameter d has a size such that said metal nanofiller particle can be embedded into a three pocket formed when said three said metal filler particles are placed on a plane so as to be mutually in contact, and said average particle diameter X has a size such that the gaps that remain within said three pocket are filled.
