Abstract
A communication system comprises a first conductor member in which a first signal line is connected at a connection position other than end portions on a surface of the first conductor member, a second conductor member connected with a second signal line, and a communication control unit that controls wireless communication by electromagnetic coupling between a first coupler including the first conductor member and a second coupler including the second conductor member. A distance between the connection position and a farthest point from the connection position on the surface of the first conductor member is equal to or less than a quarter wavelength corresponding to a signal to be used in communication by the communication control unit.
