<p>PROBLEM TO BE SOLVED: To surely ground the antenna case of a storage type antenna and to fix the case to a multilayer printed board. SOLUTION: The multilayer printed board 3 of a portable radio equipment body 10 has an intermediate ground layer 4. On the surface of the multilayer printed board 3, a groove 5 is formed along the mounting location of an antenna case 2. On the bottom surface of this groove 5, the intermediate ground layer 4 is exposed. On the intermediate ground layer 4 exposed on the bottom surface of the groove 5, a conductive elastic body 6 having electrical conductivity is placed. This conductive elastic body 6 is formed by using conductive rubber material and conductive resin material, etc. On the conductive elastic body 6, the antenna case 2 is placed, and at the inside of the portable radio equipment body 10, a pressure contact is performed for the antenna case 2.</p> |
