摘要
According to one embodiment, a living body detection sensor includes a substrate, a signal generation unit, a first conductor, a second conductor, and a detection unit. The substrate includes a reference potential electrode and a dielectric material. The signal generation unit generates a first signal, the signal generation unit is provided on the substrate. The first conductor receives the first signal, the first conductor is separated from the substrate. The second conductor t receive the first signal sent from the first conductor, the second conductor is separated from the substrate. The detection unit receives the first signal outputted from the second conductor and detects an electric field produced between the first conductor and the second conductor, the detection unit is provided on the substrate. The living body detection sensor detects whether a living body is close to the living body detection sensor.
