Abstract
An anisotropic conductive film including conductive particles arranged uniformly in a single layer and capable of supporting fine-pitch connection is produced by: drying a coating film of a particle dispersion in which conductive particles are dispersed in a dilute solution of a thermoplastic resin that forms a coating after drying, whereby a conductive particle-containing layer is formed in which the coated conductive particles coated with the dried coating of the dilute solution of the thermoplastic resin and arranged in a single layer stick to the dried coating film; and laminating an insulating resin layer onto the conductive particle-containing layer.

A method of producing an anisotropic conductive film, the method comprising:
- drying a coating film of a particle dispersion in which conductive particles are dispersed in a dilute solution of a thermoplastic resin that forms a coating after drying, whereby a conductive particle-containing layer is formed in which the coated conductive particles coated with the dried coating of the dilute solution of the thermoplastic resin and arranged in a single layer stick to the dried coating film;
- and laminating an insulating resin layer onto the conductive particle-containing layer.
An anisotropic conductive film comprising:
- a conductive particle-containing layer including a dried coating film of a dilute solution of a thermoplastic resin and coated conductive particles that are coated with a dried coating of the dilute solution of the thermoplastic resin and stick to the dried coating film while arranged in a single layer;
- and an insulating resin layer laminated onto the conductive particle-containing layer.
