2. Description of the Related Art In recent years, portable terminals such as smart phones or tablet PCs have been widely used and popularized due to the development and popularization of information communication technologies. At present, the portable terminal has a built-in function such as Internet, game, DMB, MP3, camera, etc. in addition to a telephone communication function, so that a variety of functions can be used by one device. In addition, It is becoming beautiful.

Since a portable terminal such as a smart phone is not only expensive, but also sensitive to impact, a cover or case for a portable terminal capable of protecting the portable terminal is mounted and used. Such covers and the like simultaneously perform not only the function of protecting the portable terminal from external impact but also the function of enhancing the aesthetic appearance. The cover is made of a cover made of a synthetic resin material of a hard material, a synthetic resin of a flexible material such as polyurethane or silicone Covers made of ash, and covers made of leather. Particularly, in recent years, a number of portable terminal cover products have been released in a variety of colors, materials, and designs as a function of a portable terminal as a means for indicating user's personality, etc., beyond the role of an electronic device performing various functions It is a situation.

Reflecting this tendency, by adhering a material such as a film printed with a color or a picture or a material such as wood or leather produced in the form of a thin plate to the rear surface of a cover body injection-molded with a synthetic resin material, A cover for a portable terminal is provided.

However, in such a conventional cover for a portable terminal, it is common to attach a film or a different material to the back surface of the cover body of the portable terminal by using a double-sided adhesive agent or a general industrial adhesive agent. In such a case, There is a problem in that the adhesion property is not good in the portion where the curved surface treatment is performed, such as the edge of the substrate. Further, in this case, since the film and the heterogeneous material, which are relatively vulnerable to scratches and the like, are exposed to the outside, there is a problem that the durability may be deteriorated and the new aesthetic more than the aesthetic feeling expected by the combination of the film or the heterogeneous material can not be formed .
