Abstract
An anisotropic conductive film includes conductive particles disposed in an insulating resin layer. Zigzag arrangements are arranged at a predetermined pitch in an x direction on an xy plane in a plan view of the anisotropic conductive film with positions thereof in a y direction being periodically altered. The zigzag arrangements each include an arrangement Rb and an arrangement Rc repeatedly provided at predetermined intervals in the y direction. The arrangement Rb includes the conductive particles arranged at a positive inclination, and the arrangement Rc includes the conductive particles arranged at a negative inclination. This configuration can form a pseudo random regular disposition.
