This elastic wave filter is provided with: series resonators (10a-10c) formed on a first piezoelectric substrate (12); parallel resonators (30a, 30b) formed on a second piezoelectric substrate (32) having a different cut angle from the first piezoelectric substrate (12); a package substrate (50) to which the series resonators (10a-10c) and the parallel resonators (30a, 30b) are mounted; and wiring (58) that is provided to the package substrate (50) and electrically connects the series resonators (10a-10c) and the parallel resonators (30a, 30b). |
