Abstract
A low pass filter includes a first terminal pair, a second terminal pair, a first coil connected in series between the first terminal pair and the second terminal pair and including a first coil conductor wound around a winding axis, and a second coil connected in parallel between the first terminal pair and the second terminal pair, including a second coil conductor wound around the winding axis, magnetically coupled to the first coil. An area of the first coil conductor is larger than an area of the second coil conductor.
