Abstract

An advantageous effect of a low-pass filter that reduces high-frequency noise can be obtained by including an input terminal that extends from a front surface to a rear surface of a multilayer circuit board including a double-sided circuit board; a first wiring conductor having an end connected to the input terminal on the rear surface of the multilayer circuit board; a first via that extends from an other end of the first wiring conductor to the front surface of the multilayer circuit board; a second wiring conductor having an end connected to the first via on the front surface of the multilayer circuit board; and a first input capacitor disposed on the second wiring conductor; by being conductive due to the input terminal and the first via being configured in series; and including the first input capacitor.
