Anisotropic conductive film, connected structure, and method for manufacturing a connected structure

The present invention is to provide an anisotropic conductive film that excels in dispersing conductive particles and trapping the particles, and maintains conduction reliability even between narrow-pitched terminals. By a method for manufacturing an anisotropic conductive film containing conductive particles, the conductive particles are buried in grooves in a sheet having the grooves regularly formed in the same direction, the conductive particles are arranged, a first resin film having a thermo-setting resin layer formed on a stretchable base film is laminated on the surface of the sheet on the side of the grooves to transfer and attach the conductive particles to the first resin film, the first resin film is uniaxially stretched in a direction other than the direction perpendicular to the array direction of the conductive particles, and a second resin film is laminated.
