[0026] As illustrated in FIG. 1 below, the attachment pad for an accessory of a smart device according to the present invention comprises a rear cover (300) attached to the rear portion of a protective case (90) of a smart device (S) and a magnetic portion (210) mounted on the rear cover, thereby attaching an accessory (B) through the magnetic force of the magnetic portion of the rear cover attached to the rear portion of the protective case.

[0027] Additionally, referring to FIG. 2, the rear cover (300) comprises a base film (120), an epoxy layer (100) formed by applying epoxy to one side (101) of the base film, and a design layer (130) formed on the other side (102) opposite to the one side (101) of the base film on which the epoxy is applied.

[0028] In addition, it is preferable that the base film (120) and the epoxy layer (100) be formed transparently so that the design printed on the design layer (130) is visible to the user.

[0029] Additionally, a concave portion (201) is formed on the other side (102) of the base film (120), and a convex portion (202) corresponding to the concave portion is formed on the one side (101).

[0030] And the above-mentioned concave portion (201) is provided with a storage portion (200) in which a magnet (210) can be stored.

[0031] Additionally, referring to FIGS. 2 and 3, on one side where the convex portion (202) is positioned, epoxy is applied while the convex portion (202) is formed so that the surface of the epoxy layer (100) forms a flat plane.

[0032] And if the thickness from the bottom surface of the design layer (130) to the upper surface of the epoxy layer is called the first thickness (t1) and the thickness from the inner surface of the concave portion (201) of the base film (120) to the upper surface of the epoxy layer is called the second thickness (t2), it is preferable that the second thickness (t2) and the first thickness (t1) are not formed to be the same.

[0033] In addition, when the magnet (210) is stored in the storage portion (200), it is preferable that the thickness in the storage direction of the magnet be t2 + t3 < t1.

[0034] Therefore, when the above magnet is stored in the above storage portion and attached to the rear surface of the above protective case (90), the base film (120) is attached so that it does not lift up due to the magnet, thereby making the appearance of the case beautiful and improving the adhesion of the accessory.

[0035] Meanwhile, referring to FIG. 4, a molding die is provided to form a concave portion (201) and a convex portion (202) on the base film (120). The molding die is formed with a first die (410) having a protrusion (411) corresponding to the concave portion and a second die (420) having an indentation (421) corresponding to the convex portion. The base film is placed between the first die and the second die, and then heat-pressure is applied to form the concave portion and the convex portion on the base film.

[0036] Additionally, referring to FIGS. 1 to 3, the magnet (210) is formed with a first magnet (211) that has a hollow shape inside and forms a closed loop, and a second magnet (212) formed in a straight shape, and the first magnet and the second magnet are arranged to be fitted into the storage part and then attached to an adhesive film (213) so as to maintain the arrangement.

[0037] In addition, before applying epoxy to one side (101) of the base film (120), a convex portion is formed on one side of the base film, and the epoxy is applied while the convex outer surface, which is the outer surface of the convex portion, is formed.

[0038] And the thickness of the epoxy coating is applied to cover the convex outer surface, and at this time, as the other side of the base film is positioned parallel to the ground, the surface of the epoxy layer (100) is formed parallel to the one side due to its own weight.

[0039] Additionally, the design layer (130) formed on the other surface is formed after the epoxy layer (100) is formed, and the design layer first forms a picture layer (130a) containing a picture.

[0040] And, in order to protect the above picture layer, a protective layer (130b) is formed on the surface of the above picture layer. After forming the epoxy layer first, various types of design layers are formed according to the type of picture.

[0041] That is, the magnet (210) is provided in a state attached to the adhesive film (213), and the rear cover is provided separately as described above.

[0042] Therefore, the magnet and the back cover can be packaged separately and sold as products, and users can purchase the back cover and the magnet separately and use the magnet attached to the back cover.

[0043] In addition, as the drawing layer (130a) and the protection layer (130b) are executed while the concave inner surface is formed, the drawing layer and the protection layer are also formed on the concave inner surface, so that the drawing formed on the concave inner surface and the other surface is formed continuously without discontinuity.

[0044] Additionally, the magnet (210) is positioned inside the storage portion that encloses the concave inner surface, so that when viewed from the side where the epoxy is applied, the magnet is positioned so that it is covered by the picture layer (130a) and the protective layer (130b), and thus the magnet is not visible.
