A processing device (2) includes an analog circuit block (6), a digital circuit block (7), a casing (12) which houses elements including (6) and (7) and serves as a conductive shield member, and a connecting connector (13) which has functions, for example, of electrically connecting the casing (12) and a first ground terminal (6a) provided in the analog circuit block (6). Level of noise signals generated from the analog circuit block (6) is lower than the level of noise signals generated from the digital circuit block (7). Therefore, when the casing (12) is electrically connected to the first ground terminal (6a) provided in the analog circuit block (6), the casing (12) can maintain a stable potential thereby more effectively working as the conductive shield member. Thus, leakage of the noise signals generated at driving of internal electronic circuitry is effectively suppressed in an electronic apparatus such as a receiving apparatus.
