Abstract: An anisotropic conductive film configured to suppress flowing of conductive particles attributable to the flowing of an insulating resin layer at the time of anisotropic conductive connection, improve the conductive particle capturing properties, and reduce short circuits has a conductive particle dispersion layer including the conductive particles dispersed (or distributed) in the insulating resin layer. The insulating resin layer is a layer of a photo-polymerizable resin composition. The surface of the insulating resin layer in the vicinity of each of the conductive particles has an inclination or an undulation with respect to the tangent plane of the insulating resin layer in the center portion between the adjacent conductive particles.

Abstract: A protective element is provided that is capable of stopping heat generation of a heat generation resistor after all of fuse elements are surely blown out in a case where the power is distributed from a specific power distribution path. The protective element can be configured to control blowout times of a plurality of respective fuse elements in such a manner that other fuse elements are blown out prior to the blowout of a specific fuse element in a case where the power is distributed from the specific power distribution path connected with the specific fuse element among the plurality of fuse elements.
