PROBLEM TO BE SOLVED: To provide a television receiver provided with the ground structure of a tuner for remarkably reducing undesired radiation resulting from leakage of a radio wave emitted from a built-in oscillation circuit to the surrounding of the television receiver. SOLUTION: The ground structure of the tuner 2 is characterized in that the tuner 2 incorporating the oscillation circuit 1 is fixed to a board 4, the structure is provided with: a first ground 5 for grounding legs 14 of a conductive part of the tuner 2 facing the board 4 and the conductive part of the board 4; and a second ground 7 for grounding the conductive part of the tuner 2 not facing the board 4 and the conductive part other than the board 4 by way of a lead wire 6, and an end of the lead wire 6 at the side of the tuner 2 is connected to the vicinity of the oscillation circuit 1. The connection between the tuner 2 and the lead wire 6 can be made by using connection terminals 8 attachable to/detachable from the both. Alternatively, a U-shaped connection element can be provided to the end of the lead wire 6 to clamp a tuner pack 10. Alternatively, a washer 11 can be provided to the end of the lead wire 6 and tightened to an RF terminal with a nut 13. COPYRIGHT: (C)2006,JPO&NCIPI
