on the surface of the domain the domain is elongated and oriented to one direction substantially perpendicular to the thickness direction of the adhesive film as a consequence even if the amount of inorganic substance added to the adhesive film is reduced the adhesive film will be effectively provided with a high elastic modulus and a low cte in its oriented direction particularly if the domain is in the form of slender fibers the inorganic substance will effectively provide the adhesive film with a high elastic modulus and a low cte at a lower concentration due to reduction of the addition amount of the inorganic substance the resulting adhesive film will give once cured a cured product having toughness and high adhesive force furthermore the uncured adhesive film will be strong enough that the handling of the green sheet will be easy the preferred domain consists of an elastic body elastic polymer such as a thermoplastic resin or a rubber like polymer and is easily deformed this is due to the fact that such a domain can be easily oriented to a specified direction and modified to take a fibrous shape when the adhesive film is produced as described below the thermoplastic resin may include polyvinyl alcohol polyvinyl acetate and silicone resins or a homopolymer of an acrylate a methacrylate an acrylic amide or an acrylonitrile or a copolymer of two or more.
