摘要： 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.
