Abstract: An object of the invention is to transmit a waveform suitable for the reception of signals, while suppressing an increase in man-hours needed for design. A transmission-reception device (2) includes: an antenna element (21) which is terminated at a virtual ground point side of the antenna element by a terminating element (213); a conductor plane (23) which has a predetermined potential and surrounds the antenna element (21); and a transmission circuit (25) that outputs a differential signal to both ends of the antenna element (21). An interval between the conductor plane (23) and a first outer edge (214) of the antenna element (21) is shorter than an interval between the conductor plane (23) and a second outer edge (215) of the antenna element (21).
