Abstract: An anisotropic conductive film includes, as conductive particles for anisotropic conductive connection, metal particles such as solder particles having on the surface an oxide film. In this anisotropic conductive film, the metal particles are contained in an insulating film and regularly arranged as viewed in a plan view. A flux is disposed to be in contact with, or in proximity to, at least one of ends of the metal particles on a front surface side of the anisotropic conductive film and a rear surface side of the anisotropic conductive film. Preferable metal particles are solder particles. Preferably, the insulating film has a structure of two layers, and the metal particles are disposed between the two layers.
