1. A radio module connecting a radio circuit to an antenna via a signal line, comprising:
a circuit board supporting the radio circuit, the circuit board comprising a ground pattern, a first surface, that faces a human body, and a second surface opposite to the first surface; and
a passive conductor provided on the second surface, the conductor bypassing part of a current flowing on the ground pattern from the antenna when the antenna is used, the conductor having a proximal end and a distal end, the proximal end being directly connected to the ground pattern and positioned within 1/4 of a wavelength of the radio frequency signal of a power supply point of the antenna at which distribution of the current assumes a maximum value, and the distal end being open.
