  "textContent": "A communication apparatus includes a power transmission coil and a power transmission circuit that performs wireless power transmission to another communication apparatus at a predetermined power transmission frequency via the power transmission coil. The other communication apparatus includes a power reception coil coupled to the power transmission coil with at least either of an electric field or a magnetic field. In addition, the communication apparatus includes a receiving antenna and a receiving circuit that receives via the receiving antenna a signal transmitted from the other communication apparatus via a transmitting antenna of the other communication apparatus. Furthermore, the communication apparatus includes a filter circuit that suppresses a signal of the power transmission frequency, which is to be input from the receiving antenna to the receiving circuit due to the wireless power transmission by the power transmission circuit.",
