Abstract:
A first filter of a multiplexer includes serial resonators and parallel resonators that are acoustic wave resonators. A first of the serial resonators that is closer to a common terminal than the other serial resonators is connected to the common terminal without the parallel resonators interposed therebetween. Each of the elastic wave resonators includes a substrate having piezoelectricity, an IDT electrode provided on the substrate, and a dielectric layer provided on the substrate to cover the IDT electrode. A thickness of the dielectric layer of the first serial resonator is smaller than a thickness of each of the dielectric layers of the remainder of the elastic wave resonators.

Claim (Index 6):
A multiplexer comprising:\n a common terminal; a first terminal; a second terminal; a first filter disposed on a first path connecting the common terminal and the first terminal to each other and that includes a plurality of elastic wave resonators; and a second filter disposed on a second path connecting the common terminal and the second terminal to each other and that has a pass band higher in frequency than a pass band of the first filter; wherein the plurality of elastic wave resonators include:\n one or more serial resonators that are disposed on the first path; and \n two or more parallel resonators each of which is disposed on a path connecting a node on the first path and a ground to each other; \n the two or more parallel resonators include a first parallel resonator located on a side of the common terminal and a parallel resonator located on a side of the first terminal when seen from a first serial resonator that is one of the one or more serial resonators and that is closer to the common terminal than a remainder of the one or more serial resonators; each of the plurality of elastic wave resonators includes a substrate having piezoelectricity, an IDT electrode including a pair of comb-shaped electrodes that are provided on the substrate, and a dielectric layer provided on the substrate so as to cover the IDT electrode; and the dielectric layer of at least one of the first parallel resonator and the first serial resonator has a thickness smaller than a thickness of the dielectric layer or layers of a remainder elastic wave resonator/resonators.
