    Abstract: A configuration that reduces a parasitic capacitance between wires is achieved at a low cost. Disclosed is an acoustic wave filter provided with a piezoelectric substrate 1, resonators 2a and 2b that include a comb-shaped electrode formed on the piezoelectric substrate 1, a wiring portion 3 that is connected to the comb-shaped electrode, and a dielectric layer 4 formed to cover the comb-shaped electrode. The wiring portion 3 is provided with a lower layer wiring portion 3d that is disposed in the same layer as the comb-shaped electrode and an upper layer wiring portion 3e that is disposed on the lower layer wiring portion 3d. The upper layer wiring portion 3e includes a region that has a wider electrode width than the electrode width of the lower layer wiring portion 3d.

    Abstract: An elastic wave device includes resonators having a piezoelectric substrate, a resonation unit formed on the piezoelectric substrate, and reflectors formed on respective sides of the resonation unit on the piezoelectric substrate, and bumps formed on the piezoelectric substrate. The resonators are configured such that two or more split resonators are connected in parallel, and a bump is formed in a region sandwiched between reflectors of the split resonators.
