PROBLEM TO BE SOLVED: To provide a tuner unit on which a plurality of tuner circuits are mounted, capable of integrating a plurality of tuners into a single unit for simultaneous operation, by enhancing a shield between a plurality of tuners. SOLUTION: The tuner unit comprises a circuit board (111) on which a first tuner circuit (131) for receiving a first broadcast and a second tuner circuit (132) which is adjoined to the first tuner circuit (131) to receive a second broadcast are mounted. The circuit board (111) comprises a through-hole (111a) between the first tuner circuit (131) and the second tuner circuit (132). A shield (251) engages with the through-hole (111a) of the circuit board (111) for shielding the first tuner circuit (131) from the second tuner circuit (132). COPYRIGHT: (C)2007,JPO&INPIT
