ABSTRACT:
To provide a laminated band-pass filter comprising at least two band-pass filters without reducing the Q factor of strip line conductors constituting the band-pass filters. A laminated band-pass filter comprises an integrated device formed by laminating and integrating a plurality of dielectric layers together, a plurality of internal grounding conductors formed inside the integrated device, and two band-pass filters sandwiched between two of the plurality of grounding conductors and formed inside the integrated device. One of the band-pass filters has strip line conductors, and the other has strip line conductors. The two band-pass filters are formed in different areas with a boundary between these areas corresponding to a predetermined cross section substantially perpendicular to the grounding conductors.
