Abstract:
A signal electrode (11A) and a ground electrode (11B) are disposed respectively on surfaces of a case (10). In this way, the signal electrode (11A) and the ground electrode (11B) do not come into contact with any electric component, such as a transmission circuit (21), disposed inside the case (10), and thus a reduction in an electric field (Ec) induced in an electric-field transmission medium can be prevented. In addition, a certain distance between the signal electrode (11A) and the ground electrode (11B) is kept, and thus a reduction in the electric field (Ec) induced in the electric-field transmission medium can be prevented. Furthermore, the contactability between the signal electrode (11A) and the electric-field transmission medium is improved, and thus the electric field (Ec) induced in the electric-field transmission medium can be increased.
