Abstract
A low pass filter includes a first via-hole conductor connected to a first end portion of a first inductor and a third end portion of a second inductor and extending to another side in a lamination direction with respect to a second end portion of the first inductor and a fourth end portion of the second inductor, and a first capacitor electrically connected in parallel with at least a portion of the first inductor and a portion of the second inductor and defined by a first capacitor conductor layer. The low pass filter allows the interval between attenuation poles to be easily adjusted.
