A built-in antenna for a portable terminal is provided to obtain high quality of the terminal, by preventing the degradation of radiation sensitivity of the antenna due to finger touch of a user. A built-in antenna includes a main body(110) and a sub body. The sub body performs an open/close operation in the main body, and has a slave board(20) in the inside. An electrical connection unit(40) connects the main body and the sub body electrically. An antenna radiator(30) is mounted in one side of the slave board in the same direction as a portable terminal(100), and is fed to a main board(10) through the slave board and the electrical connection unit. The built-in antenna is located in the side of the sub body separated from a head of a user.
