PURPOSE:To improve the isolation property by providing at least more than two of earth connection terminals by cutting on outward on about a straight line combining at least a pair of contact terminals in a shield case and between the contact terminals. CONSTITUTION:At the front side surface and at the right and the left sides of a shield case 6, plural earth connection terminals 10 cut out toward the outer side and erected from the bottom surface of the case 6 are provided. And the earth connection terminals 10 are arranged two each between contact terminals 5a and 5b, and between 5b and 5c respectively, and the earth connection terminals 10 are furnished close to the contact terminals 5a, 5b, and 5c. When a contact A closes or opens a high-frequency signal in such a condition, the contact terminals 5a and 5b, for example, are closed to form a closed circuit and the isolation property between this closed circuit and the opened circuit between the contact terminals 5b and 5c which is apart from the high-frequency signal transmission side can be made extremely high. |
