PROBLEM TO BE SOLVED: To solve a problem in that although electrical connection with a print circuit board is made using a conductive elastic body in order to stabilize device performance, it is necessary to ensure the contact pressure of an elastic body, which enables the retention of contact pressure for a long period of time in order to ensure a contact grounding surface in a limited range due to space saving for component-mounting space, resulting from a unit size reduction and in order to cope with characteristic degradation resulting from use environment and change with aging, as in vehicle high frequency antenna ground.SOLUTION: A printed circuit board having a ground pattern is disposed between a resin case formed from a dielectric body and a metal member provided on the resin case. A conductive elastic body having a conductive contact is interposed between the ground pattern of the printed circuit board and the metal member. A plurality of projecting parts for bringing the conductive elastic body into pressure contact is provided on a contact face of the metal member, which is disposed in contact with the conductive elastic body. |
