<P>PROBLEM TO BE SOLVED: To provide a band pass filter capable of further improving damping characteristics on the higher frequency side of a passband, a wireless communication module with the same, and a wireless communication apparatus. <P>SOLUTION: A band pass filter 1 comprising a single resonator and a composite resonator is laminated so that an extending direction of strip-shaped electrodes 22d, 23d, 24d and 25d, and an extending direction of electrode fingers 24a, 25a, 29a and 30a intersect perpendicularly. Two electrode fingers 24a and 29a disposed in the outermost parts out of a plurality of electrode fingers provided in branch electrodes 22a and 27a have bent parts 26a and 31a parallel to the extending direction of the strip-shaped electrodes when viewed from a lamination direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
