Abstract
In a ladder type filter, a first inductor is connected in series with a parallel resonator. A second inductor is connected in parallel to a series resonator. The resonant point of the parallel resonator having the first inductor connected in series and the anti-resonant point of the series resonator developed on the lower frequency side of the resonant point of the series resonator, caused by the second inductor connected in parallel, substantially coincide with each other.
