An object of the present invention is to provide a connection sheet that can enhance the electrical continuity between wirings to be connected, and can promote a reduction in thickness and space saving of a connection portion. The connection sheet of the present invention is a connection sheet used for electrical connection of a flexible flat cable having a plurality of wirings, arranged in parallel corresponding to the plurality of wirings in plan view, and conductive particles and a binder thereof And a plurality of strip-like conductive paste portions, and an adhesive portion that is disposed at least between the plurality of conductive paste portions and mainly contains a thermoplastic resin. The adhesive portion may be disposed so as to surround the plurality of conductive paste portions in a plan view. The average thickness of the conductive paste portion and the average thickness of the adhesive portion may be the same. The average width of the conductive paste portion may be smaller than the average width of the wiring. A pressure-sensitive adhesive part disposed in the same layer as the conductive paste part and the adhesive part may be further provided.
