PROBLEM TO BE SOLVED: To provide a communication device in which transmission power is reduced and downsizing and thinning are easy.SOLUTION: A communication device comprises a substrate, a line having inductive reactance, a communication part, and a variable capacitance element. The substrate includes a ground part and a dielectric part laminated on the ground part, and a first surface includes the ground part and a second surface on the side opposite to the first surface includes the dielectric part. The line is provided on the second surface side. The communication part is provided on the second surface and connected to one end of the line and the ground part. The variable capacitance element has a conductor connected to the other end of the line and electrostatic capacitance between the conductor part and the ground part is variable when a human body touches or comes close to the conductor part. |
