PURPOSE: A tuner module is provided to prevent mutual interference of each different signals inputted for each connector. CONSTITUTION: A radio frequency switching IC(400) is mounted in one side of a circuit board(300). The radio frequency switching IC selects a terrestrial signal and a cable signal. A connection piece(500) is arranged to both sides of t eh radio frequency switching IC. A shielding wall(600) is expanded along the edge of a connection piece. The shielding wall shields the radio frequency switching IC with an external wall.
