Abstract
There is provided with a portable communication device which can perform proximity contactless communication without reducing a distance capable of performing the proximity contactless communication thereby to improve convenience and prevent degradation of the characteristics of the proximity contactless communication.
In a mobile communication device 1 with a proximity contactless communication function, antennas 14A to 14C for performing the proximity contactless communication with an external proximity contactless communication device 2 are provided on the plural surfaces of the casing 10 of the mobile communication device 1. Each of the antennas 14A to 14C has one or more loops and the antennas 14A to 14C are coupled in series.
