Abstract: A mobile terminal, comprises: a case including a conductive metal part; a main board mounted inside the case and having a power supply part and a ground surface; a first antenna radiator disposed so as to be spaced from the power supply part to the first antenna radiator; a power supply line for electrically connecting the power supply part to the first antenna radiator and ground line for electrically connecting the ground surface to the metal part and the first antenna radiator, thereby preventing a decrease in the performance of an antenna since the formation of an electromagnetic field between the case of a metallic material and the main board can be minimized even if the metallic material is used for the case.
