<p>PROBLEM TO BE SOLVED: To with a simple constitution a structure for grounding a high-frequency circuit substrate and a radio wave shielding, which enables sure grounding of the high-frequency circuit substrate and the radio wave shielding. SOLUTION: A metal box body 1, a high-frequency circuit substrate 2 mounted in the metal box body 1 and a shielding frame 3 which, together with the metal box body 1, holds the high-frequency circuit substrate 2 in between and covers it are provided to a structure for grounding a high-frequency circuit substrate and a radio wave shielding, which is provided with a recessed part provided to a part of a surface mounted with the substrate of the metal box body 1 and an elastic body 7 inserted into the recessed part. By attaching the shielding frame 3, the elastic force of the elastic body 7 acts, so that a grounding surface of a circuit-formed surface of the high-frequency circuit substrate 2 adheres tightly to the bottom part of a partition wall 6 of the shielding frame 3, for grounding and radio wave shielding.</p> |
