Abstract
An acoustic wave element includes: resonatorseach including an electrode to excite acoustic waves; a power supply wiring portionthat is disposed so as to connect the resonatorselectrically; a piezoelectric substrateon which the resonatorsand the power supply wiring portionare formed; a second mediumthat is formed on the piezoelectric substrateso as to cover the resonators; and a third mediumthat is formed on the piezoelectric substrateso as to cover at least the second mediumand the power supply wiring portion. A side surfaceof the power supply wiring portionthat is in contact with a surface of the piezoelectric substrateforms an obtuse first angle θ with respect to the surfaceof the piezoelectric substrate
