Abstract
In a communication device, electric circuits other than an antenna are enclosed in a shielding member made of a material that shuts off radio waves, and the antenna is enclosed by disposing in front thereof a radio wave absorbing member that attenuates radio waves in a predetermined frequency band. Thus, unnecessary electromagnetic emission is alleviated while satisfactory communication quality is secured.
