ABSTRACT:
There are disclosed a highly packed, mixed conductive powder with a relative packing density of at least 68%, a process for producing the same, a conductive paste using the mixed conductive powder and a process for producing the same, as well as a sheet and a sheet with attached film using the mixed conductive powder. This mixed conductive powder comprises substantially monodispersed conductive scale-like particles (A1) and conductive substantially spherical particles (B1). Or, this mixed conductive powder comprises substantially monodispersed, conductive, substantially spherical particles (A2) and conductive substantially spherical particles (B2) with a smaller particle diameter than that of the substantially spherical particles (A2).
