Abstract
Provided is an electronic device that is provided with a filter circuit that suppresses the effects of electromagnetic noise propagated through space from a circuit board and reduces parasitic inductance, and can output a voltage with adequately reduced noise. To solve the above problem, in an electronic device provided with a cabinet (), a circuit board () provided in the cabinet, an output terminal () that passes through a through hole provided in the cabinet and outputs the output of the circuit board to the outside, the present invention constructs a loop composed of a filter means () having a filter capacitor (), an output terminal, a cabinet, and wires () for connecting these parts. The wire () connected to the cabinet is connected to a position close to the output terminal, and reduces the size of the loop. In addition, a shield () is provided between the filter means and the circuit board.
