Abstract: A cationically polymerizable anisotropic conductive film is provided. The cationically polymerizable anisotropic conductive film includes an alicyclic epoxy compound and achieves storage life property better than known anisotropic conductive films while ensuring curing temperature and connection reliability equivalent to known anisotropic conductive films. The anisotropic conductive film contains a binder composition containing a film forming component and a cationically polymerizable component, a cationic polymerization initiator, and conductive particles. The anisotropic conductive film contains a quaternary ammonium salt-based thermal acid generator as a cationic polymerization initiator and an alicyclic epoxy compound and a low polarity oxetane compound as a cationically polymerizable component.
