Abstract
A multiplexer includes: a filter located on a surface of a substrate and including first series and parallel resonators and a first wiring line; and another filter located on another surface of another substrate and including second series and parallel resonators and a second wiring line, each of first resonators among the second series and parallel resonators overlapping with the first series and parallel resonators, and/or the first wiring line, each of second resonators other than the first resonators among the second series and parallel resonators overlapping with none of the first series and parallel resonators and the first wiring line, when capacitances of series and parallel resonators in first basic sections including the first resonators are represented by Csand Cp, and capacitances of series and parallel resonators in second basic sections not including the first resonators are represented by Csand Cp, Cp/Csbeing less than Cp/Cs
