PROBLEM TO BE SOLVED: To provide a communication device suitably designed for further reduction in power consumption.SOLUTION: A communication device comprises a power supply unit, communication unit, and power transmission unit. The communication unit outputs an RF (Radio Frequency) signal when power is supplied from the power supply unit. The power transmission unit comprises a first conductor connected to the power supply unit, and a second conductor spaced apart from the first conductor and connected to the communication unit. The power supply unit, the power transmission unit, and the communication unit are serially connected in the described order.SELECTED DRAWING: Figure 1ACOPYRIGHT: (C)2019,JPO&INPIT【課題】消費電力量のさらなる低減に適した通信デバイスを提供する。【解決手段】この通信デバイスは、電源部と、通信部と、電力伝送部とを有する。通信部は、電源部からの電力の供給によりRF(Radio Frequency)信号の出力を行う。電力伝送部は、電源部と接続された第1の導電体と、その第1導電体と離間して設けられて通信部と接続された第2の導電体とを含む。電源部と電力伝送部と通信部とがこの順に直列に接続されている。【選択図】図1A
