Claim:
1. A communication control device which is mounted on a mounting board, the device comprising: an antenna electrode to which an antenna is connected; a power supply circuit which is connected to the antenna electrode; a communication circuit which is connected to the antenna electrode, a first signal path connecting the antenna electrode and the communication circuit extending along the first side; and a second signal path connecting the antenna electrode and the power supply circuit extending along a third side that shares the corner portion and is perpendicular to the first side, wherein the power supply circuit includes: wherein the second signal path includes a signal path for transmitting a signal from the antenna electrode to the rectifier circuit, wherein the rectifier circuit is disposed along the third side, wherein the DC/DC converter is disposed so as to be separated from the rectifier circuit in a direction of a fourth side facing the third side, wherein the mounting board comprises a multi-layered substrate including a plurality of conductive layers, wherein the antenna electrode, the power supply circuit, the communication circuit, the first signal path, the second signal path, and a first ground pattern for connection to a ground potential are formed on a first conductive layer of the plurality of conductive layers constituting the first principal surface in the mounting board, wherein the first ground pattern is formed in a vicinity of the first signal path and the second signal path, and wherein the first ground pattern has a slit formed along at least a portion of the second signal path, in a region interposed between the first signal path and the second signal path.
