Abstract: A wireless receiving device of the present invention is so arranged that (i) a high-frequency circuit section is provided on a front surface of a printed board and (ii) a digital video signal processing section and a wireless LAN digital signal processing section are provided on a back surface of the printed board. Further, an earth pattern is provided in a middle position between the front and back surfaces of the printed board, so that (i) the high-frequency circuit section and (ii) the digital video signal processing section and the wireless LAN digital signal processing section are shielded from one another using electromagnetic shielding by the earth pattern. Thus, when members that are commonly used for the wireless LAN and for wireless video reception are formed on a single printed board in order to reduce the size of the printed board, it is possible to effectively reduce the lowering of signal quality caused by the noise.
