摘要：
One embodiment of a high-frequency filter includes a band-rejection filter including a plurality of reflection-type resonance elements and a filter circuit element provided between the reflection-type resonance elements, wherein an electrical length between the reflection-type resonance elements between which the filter circuit element is provided is an odd multiple of 90 degrees in a rejection band of the band-rejection filter.
