摘要：
An object of the present invention is to provide a low pass filter that allows the interval between attenuation poles to be easily adjusted.
A low pass filter according to the present invention 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 connected in parallel with at least a portion of the first inductor and a portion of the second inductor and formed by a first capacitor conductor layer.
