To provide a technique by which a material exhibiting high adhesiveness to objects to be fixed can be selected regardless of a material used for an insulating base in an anisotropic conductor having an adhesive section. An intermediate sheet which can be attached to the base is provided between the base and adhesive section. Since the intermediate sheet is provided in this manner, adhesive materials that exhibit high adhesive force to objects to be fixed can be used for the adhesive section without the consideration for adhesive force to the base. Furthermore, adhesive force which cannot be exhibited between the adhesive section and the base in the case of direct contact of the adhesive section with the base can be exhibited.

Anisotropic conductor, method of producing the same, and anisotropic conductor-arranged sheet

Disclosed is an anisotropic conductive sheet which is equipped with an insulating base portion and a plurality of conductive portions extending through the base portion in a thickness direction thereof, which easily allows temporary fixation at a time of attachment thereof, and which, if pressurized, causes no adhesive material to be squeezed out onto the conductive contacts. An anisotropic conductive sheet includes a base portion and conductive portions exposed therethrough to form conductive contacts, with at least one of surfaces of the base portion having an adhesive portion spaced apart from the conductive contacts.
