摘要： The present invention addresses the problem of providing an installation body that, irrespective of the relative angle between a transmitter and a receiver, enables reduction in size and thickness of the transmitter and simultaneously enables improving of the probability of being able to achieve better reception of radio waves transmitted by the transmitter. In order to solve this problem, the installation body according to the present invention is provided with a conductor that is located in the vicinity of an antenna of the transmitter, in a state in which the transmitter is disposed in proximity to the installation body. The conductor is configured such that an induction current is generated therein by a drive current of the antenna. The induction current has a current component in a direction different from the direction of the drive current.
