    • A duplexer includes a ladder filter and a multimode filter that are formed on the same surface of a predetermined substrate. In this duplexer, a first comb-like electrode of the ladder filter and a second comb-like electrode of the multimode filter have the same layer structure with the same film thickness. The first comb-like electrode and the second comb-like electrode are formed with single-layer films mainly containing aluminum.
