Claim 0:
1. A multiplexer comprising:
a common terminal;
a first acoustic wave filter connected to the common terminal;
a first wiring line connecting the common terminal and the first acoustic wave filter to each other without a capacitor being connected in series between the common terminal and the first acoustic wave filter;
a second acoustic wave filter connected to a first connection node on the first wiring line;
a third acoustic wave filter connected to a second connection node on the first wiring line;
a second wiring line connecting the first connection node and the second acoustic wave filter to each other;
a third wiring line connecting the second connection node and the third acoustic wave filter to each other; and
an inductance element connected between a wiring region of the first wiring line that extends from the first connection node to the first acoustic wave filter and a ground or between the second wiring line and the ground; wherein
a length of a portion of the first wiring line extending from the common terminal to the first connection node is longer than a length of a portion of the first wiring line extending from the common terminal to the second connection node; and
the common terminal is connected to the ground by the inductance element without a capacitor.
