PURPOSE: To improve electromagnetic compatibility and effectively restrain an external noise leak or the like by filling a gap formed between an enclosure of high-frequency connector mounting structure and a high-frequency connector, with an electromagnetic shielding material. CONSTITUTION: In this high-frequency connector mounting structure, an external noise reaching an enclosure 1 or a noise reaching from another device thereto, propagates to a device internal circuit via a gap S between the enclosure 1 and the flange section 12 of a high-frequency connector 10. For the prevention of such a noise propagation, the gap S is filled with an electromagnetic shielding material 20 to absorb the noise, and the propagation of the noise to the circuit is thereby restrained. Also, frequency signal and unnecessary wave noises generated in a signal processing circuit within the enclosure 1, such as a frequency conversion circuit, are absorbed into the shielding material 20, thereby restraining the external leakage thereof. The shielding material 20 is in a fluidized state and coagulated after an application. In other words, the material 20 is formed, for example, out of iron oxide magnetite mixed with an urethane resin adhesive. |
