Among center distances between an arbitrary conductive particle and conductive particles adjacent to the conductive particle, the shortest distance to the conductive particle is a first center distance; the next shortest distance is a second center distance. These center distances are 1.5 to 5 times the conductive particles' diameter.

In such an anisotropic conductive film, the electrically conductive particles are disposed in a lattice by being arranged in first direction rows and second direction rows, and narrow and wide intervals are provided between neighboring rows in at least one of the direction rows. As a result, opposing terminals are stably connected using the anisotropic conductive film, inspection after the connecting is more easily performed, and the number of electrically conductive particles not involved in the connection are reduced and, thereby, the manufacturing cost of the anisotropic conductive film is reduced, even in FOG connections or the like with finer bump pitches.
