Abstract
A communication board mounted on an electronic device includes a plurality of antennas configured to transmit and/or receive a signal by electromagnetic induction, where each of the plurality of antennas is provided on a substrate, as a coil-shaped pattern, a semiconductor chip mounted on the substrate, the semiconductor chip including at least one of a transmission circuit which transmits a signal to the antenna and a reception circuit which receives a signal transmitted from the antenna, and an input-and-output end that is connected to the semiconductor chip via a wiring layer provided on the substrate and an electronic circuit of the electronic device. The communication board communicates with a communication board mounted on another electronic device via the antenna by electromagnetic induction.
