PROBLEM TO BE SOLVED: To obtain a wireless communication device which does not depend on a surrounding environment largely, which has stable communication characteristics.SOLUTION: A wireless communication device includes: a wireless IC chip 50 which processes a high frequency signal; and a feeding board 10 which includes a coil conductor 31, a plane conductor 35, and a matching circuit 20 connected with the wireless IC chip 50 and having a predetermined resonance frequency. The coil conductor 31 and the plane conductor 35 are connected with the matching circuit 20. When the feeding board 10 is located close to a conductor 61, the conductor 61 is disposed so as to overlap with the plane conductor 35 and avoid overlapping with the coil conductor 31 in a planar view. |
