The wireless communication device

The present invention can obtain a small, relatively long communication distance, having a stable frequency characteristic of a wireless communication device. The wireless communication device comprising: a planar radiating element, the radiating element comprises a one end portion (11a) and the other end portion (11b) of the ring portion (11); feed element (20), the power supply element (20) comprises a ring portion (11) of the end portion of the coil pattern (L1) (11a) is connected; and a wireless IC device (30), the wireless IC device (30) coil pattern (L1) is connected. Pattern coil (L1) arranged in the vicinity of the ring portion (11), and wound to: when power is supplied to the coil patterns (L1), current (I1) flows through the coil pattern (L1) flowing through the ring portion (11) current (I3) in the same direction. Pattern coil (L1) and the ring portion (11) connected in series, and coupled via a magnetic field.
