To provide an electronic device capable of reconciling an acceleration test with current consumption reduction at an ordinary operation, concerning the electronic device having a plurality of processing devices driven by different voltages, for processing an input signal, and its test method.

This device has a first processing part 31 for processing the input signal, a direct-current conversion part 32 for performing direct-current conversion of a signal processed by the first processing part, and a second processing part 33 for processing the signal subjected to the direct-current conversion by the direct-current conversion part 32. The direct-current conversion part 32 is characterized by having a current control part M12 for controlling a driving current.
