Abstract: An anisotropic conductive film which suppresses occurrence of short circuit at the time of anisotropic conductive connection, prevents reduction in capturing capability of electrically conductive particles, enables favorable pushing of electrically conductive particles and exhibits not only favorable initial conductivity but also favorable conduction reliability, contains a first electrically conductive particle group and a second electrically conductive particle group, each including a plurality of electrically conductive particles, in an insulating binder. The first electrically conductive particle group and the second electrically conductive particle group are present in a first region and a second region, respectively, which differ from each other in the thickness direction of the anisotropic conductive film and are parallel to the plane direction. Moreover, the first electrically conductive particle group and the second electrically conductive particle group differ from each other in an existence state of the electrically conductive particles.

Abstract: An electrically conductive material with which excellent conduction reliability can be achieved for an oxide layer. The electrically conductive material contains electrically conductive particles including resin core particles, a plurality of electrically insulating particles being disposed on the surface of the resin core particles and forming protrusions, and an electrically conductive layer being disposed on the surface of the resin core particles and the electrically insulating particles, a Mohs' hardness of the electrically insulating particles being greater than 7. As a result, the electrically conductive particles pierce and sufficiently penetrate the oxide layer of the electrode surface so that excellent conduction reliability can be achieved.
