<P>PROBLEM TO BE SOLVED: To provide a wireless communication device that properly inspects disconnection or poor connection of a signal line. Ž<P>SOLUTION: A wireless communication device to which an antenna and a receiver for converting a signal included in a radio wave into an electric signal are connected in order by means of a signal line includes a means for applying a DC signal to the signal line through an internal resistance, and a determination is made whether the voltage of the internal resistance on the reverse side of the means for applying a DC signal goes above a threshold during operation of the means for applying the DC signal, thus inspecting disconnection or poor connection of a signal line.
