A multiplexer includes a first filter disposed on a first signal path, a second filter disposed on a second signal path different from the first signal path, the second filter having a passband different from that of the first filter, a common connection point at which the first signal path and the second signal path are connected to each other, and an inductor disposed in series on a path connecting the common connection point and the first filter, the path being a portion of the first signal path. On the first signal path, a distance connecting the common connection point and the inductor is shorter than a distance connecting the inductor and the first filter.
