Abstract: A fault detection device executes a test signal supply process for changing a frequency of a carrier wave within a frequency range predetermined as a range of a resonance frequency of an antenna, modulating the carrier wave with a test signal as an input signal, amplifying the carrier wave that is modulated, and supplying the carrier wave that is amplified as an output target signal to the antenna. While executing the test signal supply process, the fault detection device measures an antenna current corresponding to the frequency each time the frequency of the carrier wave is changed The fault detection device detects a fault caused by a difference or a change in a characteristic of the antenna by using a value of the antenna current on a larger side among the antenna currents measured during the test signal supply process.
