In addition, the shield member 320 may be provided with a plurality of flange portions 322 and 323 extending along the outer circumferential surface. A portion 322 of the flange portions 322 and 323 may be unfolded while the rest 323 may be mounted on the shield frame 322 in a bent state toward the circuit board 180, The heat dissipating area is widened by the support portion 322.

It is preferable that the flange portion 322 in the unfolded state performs the function of the above-mentioned heat dissipation portion and is provided as a peripheral region at a position where the electronic device 182 having a high heat generation amount is disposed.

6 and 7, the heat of the local area S of the shield member 320 heated by the heat generated from the electronic device 182 is rapidly dispersed through the flange portion 322 in the expanded state And it is possible to prevent the user from sensing the heat generation phenomenon through a part of the case 101 to 103 where the electronic element 182 is located.

That is, the local region S is prevented from being intensively heated, and the heat is rapidly dispersed, thereby reducing the total calorific value.

Although the shielding structure is formed by the shield frame 310 and the shielding member 320, the present invention is not limited thereto. The shielding structure may include only the shielding member 320.

The shield member 320 may be formed of a copper alloy to increase the thermal conductivity of the shield member 320. The shield member 320 may be formed of a copper alloy, ) May be formed of stainless steel so as to maintain durability and excellent strength.

Meanwhile, a heat radiation sheet (not shown) may be attached to the shield member 320, and the heat generation sheet may be formed of graphite having high thermal conductivity.

The effect of the mobile terminal 100 according to the present invention will be described as follows.

According to at least one of the embodiments of the present invention, the heat generated from the electronic device is effectively dispersed.

Further, according to at least one of the embodiments of the present invention, the local site is prevented from being intensively heated.

Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
